Materials

Acetal

Acetal offers good temerature resistance, excellent dimensional stability and low moisture absorption. It is used in enviroments where moisture or close tolerance dimensions are needed.  It is FDA, USDA, 3A and NSF compliant.

HDPE

High Density Polyethylene. Natural color is white (translucent in thin sections).
Harder, stiffer, and more crystalline than LDPE, but higher temperature and chemical resistance. HDPE is a low cost material for strength, toughness, moisture resistance and UV resistance (when pigmented black). Some grades can be used in food contact applications when used in accordance with FDA standards.

LLDPE

Linear Low Density Polyethylene. Natural color is white (translucent in thin sections)
Softer than HDPE, and more crystalline than LDPE, LLDPE is a low cost material for high impact, low tensile, low hardness, moisture resistance applications and UV resistance (when pigmented black). Some grades can be used in food contact applications when used in accordance with FDA standards.

Nylon - 6, 6/6, 11 and 12

Natural color is white or ivory. Offers great tensile strength and good impact and abrasion resistance. High temperature and chemical resistance. The very low coefficient of friction makes it suitable for wear applications. Nylon will absorb moisture to varying degrees which can affect dimensional stability as well as some mechanical properties. Some grades can be used in food contact applications when used in accordance with FDA standards.

Polycarbonate

Natural color is clear. Maintains a good impact resistance and very high clarity. Has the maximum rigidity available as well as excellent outdoor weathering. Good dimensional stability and fairly high continuous use temperature over 250 Degrees F.

Polypropylene

Natural color is off-white translucent. Good tensile properties and stiffness at service temperatures between 260F-270F. Good impact strength but not as good as HDPE. Polypropylene is a low cost, good chemical and abrasion resistant homopolymer. Resistant to stress cracking but poor weather-ability. Some grades can be used in food contact applications when used in accordance with FDA standards

Polyurethane - Both Ether and Ester based

Natural color is transparent to translucent. Available in soft grades(60 durometer on the Shore A scale) to hard grades (99 durometer on the Shore A scale). This range of hardness and properties such as tensile and tear strength, good abrasion resistance, and good impact resistance from the harder grades makes polyurethane a versatile elastomer. Ester TPUs are tougher than Ether. They are good in applications involving grease, but will degrade in water. Ethers are good in conditions involving water, but less resistant to chemicals and oils. Excellent cut resistance. Some grades can be used in food contact applications when used in accordance with FDA standards.

PVC - Flexible and Rigid

Natural color is clear to bluish translucent. PVC has excellent weather-ability/UV resistance. Wide range of flexibility obtained by use of plasticizer. Good dimensional stability and nonflammable. Rigid PVC is very corrosion resistant but has poor abrasion resistance. Limited thermal capability. Some grades can be used in food contact applications when used in accordance with FDA standards.

PVDF - Polyvinylidene Fluoride (Kynar/Hylar)

Natural color is translucent beige to clear. Excellent in high heat applications and excellent chemical resistance, PVDF is also very UV resistant. PVDF has greater strength, wear resistance, and creep resistance than PTFE (Teflon). Good continuous use temperature up to 300 degrees F.

UHMW/PE - Ultra High Molecular Weight Polyethylene

Natural color is opaque white. Outstanding abrasion and impact resistance with a very low coefficient of friction. Excellent choice for wear applications. Some grades can be used in food contact applications when used in accordance with FDA standards.
