注：√——寿命较长、○——寿命一般、x——不可用。本表仅从耐腐性考虑，因聚四氟乙烯弹性比橡胶差，故 实际使用寿命因压力，泵行 程杂质等因素影响而异。食品橡胶专用于食品饮料行业。 note：○-means the long service life, √-means comon service life, x-means use forbidden. this table is only considered from the anti-corrosion. because the ptfe elasticity is worse than that in rubber. the actual use life will be affected because of the pressure and pump stroke factors. the food rubber specially uses for beverage industries.
