In acidic environments or require a smaller elongation, main products, general acid and heat bleach it almost has no effect, but not for outside the concentrated sulfuric acid, alkali and - 40 DEG C - 100 DEG C temperature range of use, polyester in safety work force. The degree of extensibility is about 3% (untreated).
Is widely used in cable production, it is not grease, oil, and are strong chemical resistance to alkali, ethers and aldehydes, but not for use outside of the acid, bleaching agent and - 40 DEG C - 100 DEG C temperature range, nylon in safety work force. The degree of extensibility is about 6-8%, and joined the damp, the intensity will loss more than 10%.
Almost any of the acid and alkali of PP had no effect. It has high strength and resistance to chemical environment, in environmental chemistry preferred products, use temperature range of - 40 DEG C to 80 DEG C.
