Shapes: FORMS

1: FORM AH natural

Acetal Copolymer (Unfilled)
FORM AH natural is the industry standard for porosity-free acetal. It offers a unique balance of physical properties, including high strength, stiffness, and toughness. Because it is a copolymer, it is more resistant to hot water and strong alkalis than the homopolymer (AD) version.

Technical Strength: With a tensile strength of 67 MPa and a tensile modulus of 2800 MPa, it provides the structural integrity needed for precision mechanical parts. It operates reliably in temperatures between -50°C and +100°C (long term). Its low water absorption (0.2% saturation) makes it far superior to Polyamide in humid environments.

2: FORM AH black

Acetal Copolymer (Black)
This is the UV-stabilized version of the AH natural. It retains the same high toughness and chemical resistance but is pigmented black for improved weather resistance and aesthetic appeal in visible machinery parts.

Technical Strength: It maintains the 67 MPa tensile strength and excellent sliding properties of the natural grade. It is the go-to for automotive and outdoor applications where “ghosting” or fading of the material cannot be tolerated. Like all AH grades, it is “porosity-free,” ensuring no air pockets weaken the material during heavy machining.

3: FORM AH blue

Food Grade Optical Detectable Acetal
Specifically engineered for the food processing industry, this material is colored a brilliant blue to optimize optical detection. If a fragment ever enters the production line, automated optical sensors can flag it immediately.

Technical Strength: Compliant with FDA and EU 10/2011 food contact regulations, it offers a density of 1.41 g/cm³. It shares the high stiffness and wear resistance of standard AH, making it ideal for scraper blades, funnels, and gears in food machinery where safety is the priority.

4: FORM AH GF25 natural

25% Glass Fibre Reinforced Acetal
When standard acetal isn’t stiff enough, we look at the GF25. The 25% glass fiber reinforcement creates a massive jump in mechanical performance, specifically in dimensional stability and creep resistance under load.

Technical Strength: The reinforcement increases the tensile modulus to approximately 4500 MPa, making it significantly more rigid than unfilled grades. It also raises the heat deflection temperature (HDT), allowing the part to maintain its shape under higher thermal stress. It is primarily used for structural parts in mechanical engineering.

5: FORM AD natural

Acetal Homopolymer
Manufactured from high-performance acetal homopolymer resin, this homopolymer version offers higher mechanical strength, stiffness, and hardness than the AH copolymer. It has a higher melting point and better fatigue resistance, though it is more sensitive to high-temperature hydrolysis (hot water/steam).

Technical Strength: Boasting a tensile strength of 79 MPa and a modulus of 3400 MPa, it is the “muscle” of the acetal family. It has a slightly higher melting temperature of 182°C (compared to 166°C for AH). If you need the tightest tolerances and maximum mechanical load-bearing capacity, AD is the choice.

6: FORM AD AF natural

PTFE Fiber Reinforced Homopolymer
This is a specialized grade containing uniformly dispersed low-friction fluoropolymer fibers. It is designed for applications where standard acetal’s friction isn’t low enough. The PTFE fibers create a “self-lubricating” surface that eliminates “slip-stick” and reduces wear.

Technical Strength: While slightly softer than unfilled AD, it offers an incredibly low coefficient of friction. It is the definitive material for high-speed bushings, bearings, and sliding components where external grease is prohibited or impossible to apply.

7: FORM AH ID blue

Inductive Detectable Acetal
Beyond just “blue,” the ID grade contains a metal-detectable filler. This allows standard industrial metal detectors to find plastic fragments as small as 3mm, providing an essential safety net for food and pharmaceutical packaging lines.

Technical Strength: It maintains a density of 1.49 g/cm³ (slightly higher due to the detectable fillers) and has a tensile strength of 64 MPa. It offers the perfect combination of detectability, food-grade compliance, and the high-end machining characteristics of standard POM-C.

8: FORM AH ELS black

Electrically Conductive Acetal

By adding conductive carbon black to the POM-C matrix, we’ve created a material that effectively bleeds off static charges. It is specifically designed for use in explosion-hazard areas (ATEX) or electronic assembly environments.

Technical Strength:

It features a surface resistivity of 10 kΩ to 1 MΩ it from the “insulating” range to the “conductive” range. It retains good chemical resistance and strength, making it ideal for fuel pump components, conveyor parts for electronics, and sensitive sensor housings.

9: FORM AH SD natural

Antistatic (Static Dissipative) Acetal

Unlike the ELS (conductive) grade, the SD grade contains a non-carbon antistatic agent. It is designed for applications where you need to prevent static buildup but want a “clean” material that won’t leave carbon marks or interfere with electrical signals.

Technical Strength: With a surface resistivity of 1 GΩ to 100 GΩ (gigaohms), it sits in the static dissipative range. It is natural/creamy in color (unlike the black ELS), which is often preferred for medical and cleanroom environments where visual cleanliness is as important as electrical performance.

10: FORM AH LA blue

Lubricant-Modified Acetal
This grade is an AH copolymer with a solid lubricant added to the matrix. It is designed to provide the sliding performance of the PTFE-filled grades but at the cost-effective price point of the copolymer family.

Technical Strength: The additive significantly reduces the coefficient of dynamic friction and improves the wear factor (K-factor) without compromising the material’s toughness. It is excellent for high-cycle applications like conveyor rollers and wear strips where maintenance-free operation is required.

11: FORM AH MT natural

Medical Grade Acetal Copolymer

FORM AH MT natural is a medical-grade POM-C specifically developed for the healthcare industry. It is tested for biocompatibility and is suitable for medical applications with skin and tissue contact for up to 24 hours. This material is designed to withstand standard cleaning and disinfection cycles without losing its mechanical integrity.

Technical Strength: This grade maintains a high tensile strength of 68 MPa and excellent dimensional stability, crucial for precision medical instruments. It is highly resistant to various medical-grade detergents and disinfectants. Common applications include trial implants, surgical tool handles, and diagnostic equipment components where performance and safety are non-negotiable.

12: FORM AH MT blue

Medical Grade Acetal (Blue)
This is the blue-pigmented version of the medical-grade acetal. The specific blue color is standardized in the medical field to provide quick visual identification of instruments during surgery and to differentiate between various sizes or types of medical trials and tools.

Technical Strength: It shares the same technical profile as the natural MT grade, including a density of 1.41 g/cm³ and a melting temperature of 166°C. It is fully compliant with the rigorous requirements of medical technology, offering high strength, stiffness, and chemical resistance to the superheated steam used in autoclaves (though restricted to lower temperatures compared to PEEK).

13: FORM AH LM white

Laser Markable Acetal
Standard acetal is notoriously difficult to mark permanently. FORM AH LM contains specialized additives that react to laser energy, allowing for high-contrast, permanent marking of serial numbers, logos, or barcodes without affecting the surface integrity or mechanical properties of the part.

Technical Strength: It retains all the core benefits of the AH family, including low moisture absorption and high creep resistance. It is often used in the automotive and electronics industries where permanent component traceability is required, ensuring that identifying marks remain legible even after exposure to heat, chemicals, or friction.

14: FORM AH MT black

Medical Grade Acetal (Black)

The black-pigmented medical-grade acetal is used when aesthetic requirements or specific light-absorption properties are needed in medical devices. It provides a professional, high-end finish for surgical instrumentation and diagnostic devices while maintaining all necessary health and safety certifications.

Technical Strength: Like the other MT grades, it is biocompatible and offers high mechanical strength with a yield stress of 67 MPa. Its low moisture absorption ensures that precision-machined medical parts maintain their tight tolerances even in humid clinical environments or during repeated liquid sterilization processes.
