ABOUT UHMWPE/HDPE BOARDS:Ultra-high-molecular-weight polyethylene/HIGH DENSITY POLYETHYLENE (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), or high-performance polyethylene (HPPE), it has extremely long chains, with a molecular mass usually between 2 and 6 million u. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.UHMWPE/HDPE is odorless, tasteless, and nontoxic. It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating; and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetal, and is comparable to that of polytetrafluoroethylene (PTFE, Teflon), but UHMWPE has better abrasion resistance than PTFE.UHMWPE/HDPE sheet has been used as synthetic ice in ice rinks where ambient temperatures or energy costs make it impractical to create and maintain normal ice. The material's resistance to cutting and abrasion make it highly suitable for this application.UHMWPE sheet is also cut into small blocks to be used as a brake pad material for mountain bike trials rim brakes. The material's combination of flexibility and abrasion resistance allows it to run on a roughened rim surface to lock the braked wheels extremely securely when the brake is pulled, while still wearing at a slower rate than more common bicycle brake pad materials.Mainly properties of UHMWPE/HDPE SHEETS:Items Testing Method ResultDensity D1505 0.94-1.3g/cm3Elongation at Break D638 350%Hardness D747 40Melting Point D2117 136 CentigradeVicat softening Point D1525 134 CentigradeVolume Resistance D257 1017SL-CMWater Absorption D570 <0.01%the mainly/ standard size of UHMWPE/HDPE SHEET:Thickness: 5mm/0.2”inch, 10mm/0.4”inch, 20mm/0.8”inch, 50mm/2”inch, 100mm/4”inchLength*Width: 1000*1000mm/40”inch*40”inch, 1000*2000mm/40”inch*80”inch, 1000*3000mm/40”inch*120”inch, 2000*2000mm/80”inch*80”inch, 2000*4000mm/80”inch*160”inch2*4ft; 4*4ft; 4*6ft;For more size, please contact with me--Helen Zhang.
