General Description
Plaztuff™ Hyspec Polymer sheet is a modified High Molecular Weight Polyethylene (HMWPE) made to our exact specification for the purposes of manufacturing a wide range of engineering products using extrusion welding and sheet fabrication techniques
Polyethylene’s are semi-crystalline materials with excellent chemical resistance#, good fatigue and wear resistance, and a wide range of properties. Polyethylenes provide good resistance to organic solvents, degreasing agents and electrolytic attack. They have higher impact strength, but lower working temperatures than Polypropylene. They are light in weight, resistant to staining and have very low moisture absorption rates. Polyethylenes are easy to distinguish from other plastics as they float in water.
Plaztuff ™ HMWPE is lightweight (1/8 the weight of mild steel), high in tensile strength and is as simple to machine as wood and with extrusion welding equipment is fully weldable.
Plaztuff™ is self-lubricating, offers excellent impact resistant, long wearing, has moderate abrasion resistant and is corrosion resistant. Plaztuff™ sheet is built to a high specification with a very high UV factor and performs well in all environments with good weathering properties and a 20+ UV life. Plaztuff™ is also non-toxic and non-staining and meets FDA and USDA certification acceptance for food and pharmaceutical equipment and is a good performer in applications up to 82°c

The nominal properties reported herein are typical of the product, but do not reflect normal testing variance and therefore should not be used for specification purposes. Values are rounded. The physical properties determined on test pieces cannot be used for concluding the behaviour of finished articles, since the range of variables in both the processing and shaping play a part.

Chemical Resistance Classification
E — 30 days of constant exposure to reagent causes no damage
G — Little or no damage after 30 days of constant exposure to the reagent
F — Some effect after 7 days exposure to the reagent. Solvents may cause swelling and permeation losses
N — Not recommended for continuous use
