Is food grade gloves made of pvc or tpe?
pvc：聚氯乙烯，英文简称PVC，是氯乙烯单体（VCM）在过氧化物、偶氮化合物等引发剂或在光、热作用下按自由基聚合反应机理聚合而成的聚合物。氯乙烯均聚物和氯乙烯共聚物统称之为氯乙烯树脂。PVC曾是世界上产量最大的通用塑料，应用非常广泛。在建筑材料、工业制品、日用品、地板革、地板砖、人造革、管材、电线电缆、包装膜、瓶、发泡材料、密封材料、纤维等方面均有广泛应用。
PVC: PVC, short for PVC in English, is a polymer formed by polymerization of vinyl chloride monomer (VCM) with peroxide, azo compound and other initiators or under the action of light and heat according to the free radical polymerization mechanism. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC used to be the largest general plastic in the world and has been widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
tpe：热塑性弹性体TPE/TPR，又称人造橡胶或合成橡胶。其产品既具备传统交联硫化橡胶的高弹性、耐老化、耐油性各项优异性能，同时又具备普通塑料加工方便、加工方式广的特点。可采用注塑、挤出、吹塑等加工方式生产，水口边角粉碎后100%直接二次使用。既简化加工过程，又降低加工成本，因此热塑性弹性体TPE/TPR材料已成为取代传统橡胶的最新材料，其环保、无毒、手感舒适、外观精美，使产品更具创意。因此也是一支更具人性化、高品位的新型合成材料，也是世界化标准性环保材料。
Tpe: thermoplastic elastomer TPE/TPR, also known as artificial rubber or synthetic rubber. Its products not only have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of convenient processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion, blow molding and other processing methods, and 100% of the nozzle corners can be directly reused after being crushed. It not only simplifies the processing process, but also reduces the processing cost. Therefore, thermoplastic elastomer TPE/TPR material has become the latest material to replace traditional rubber. Its environmental protection, non-toxic, comfortable feel, and beautiful appearance make the product more creative. Therefore, it is also a new type of synthetic material with more humanization and high grade, and also a world-class standard environmental protection material.
