customized polyurethane hollow rod

customized polyurethane hollow rod

Characteristics:

1. good anti-abrasion

2. wide scope for hardness :PU products hardness is shore A10-D80 about, while the common rubbers hardness is shore A60-100. Whats wore, the the elongation rate for flexibility of PUR can reach of 400-800% in its harness scope, while the NRs elongation rate is 550 even if in the most hardness of Shore A70.

3. high intensive and elongation rate.

4. excellent anti-oil capability: the anti-oil capability of the PU products is much better than butyl rubber; its anti-aging is much better than NR and other synthetic rubber; the PPG is much better than PET in the anti-hydrolysis, anti-acid/alkali capacities.

5. it has the properties of small capacitance, high intensive, insulation, sound insulation, anti-burned, anti-cold, anti-skepticism, non hygroscopy, convenience construction, it has been the indispensability materials of insulation, waterproof and plugging, and sealing in construction, transportation, oil, chemical industry, electric power , cold storage and other industrial sector.
