UD/KEVLAR Product Mould   

UHMWPE is short for Ultrahigh Molecular Weight Polymer.

It's a linear polyethylene with a molecular weight in the range of 1,000,000 to 5,000,000. The high molecular weight is what gives the polymer it's unique properties: high abrasion resistance, low coefficient of friction, highest impact resistance, exceptional noise-dampening properties. UHMWPE does not melt or flow as a molten liquid so it can not be processed by conventional plastic molding methods, at present, we only use compression molding. Cooperating with military units, our company developed bulletproof armour plate and bulletproof helmet mould, taking advantage of it excellent impact resistance property. We achieved sectional pressing and heating on one set of mould and shift from heated mould to cooled mould in the final forming stage to ensure the product cools and forms to rated temperature and rated material hardness and be released easily.

Aramid Fiber is also called polyphenylene terephthalamide fiber (In DuPont, it is called Kevlar). It's a new type of high-tech synthetic fiber with excellent properties such as superior intensity, high modulus, acidproof, alkali-resisting, and light weight.
