TPE and PP are both raw materials for manufacturing plastic products, but many material buyers may not understand the safety of TPE or PP materials? The quality of material procurement directly affects the sales profit of finished products. With the improvement of living standards, most consumers will consider environmental protection and health issues when buying plastic products. Miller will explain which TPE or PP material is safe for everyone? The material properties of the two are introduced.
　　 One, what is TPE? TPE material characteristics and application range:
　　 TPE stands for Thermoplastic Elastomer, which is a thermoplastic elastomer material. Thermoplastic means that it can be recycled and reused and can be processed by injection molding. TPE products have excellent coloring properties, are environmentally friendly and non-toxic. It can be two-shot injection molding, covering and bonding with PP, PE, PC, PS, ABS and other matrix materials, or it can be molded separately.
　　TPE overmolding handle
　　 The heat resistance of TPE is not as good as that of rubber. As the temperature rises, the physical properties decrease greatly, so the scope of application is limited. At the same time, the compression deformation, elastic recovery, and durability are inferior to rubber, and the price is often higher than that of similar rubber.
　　 Wide range of hardness, excellent transparency, gloss, and comfortable feel, widely used in adult products. Has good UV resistance, weather resistance, high temperature resistance, long-term use outdoors... TPE is also a compound of many thermoplastic elastomers (TPEE, TPA, TPO, TPV, TPU)!
　　TPE has the characteristics of safety and non-toxicity, and its environmental protection conforms to the environmental protection standards of European and American countries. Wide range of processing methods, such as injection molding, extrusion, pouring, blow molding and other processing techniques, comfortable texture, convenient surface, wide range of hardness (0-100A), can be used repeatedly, and the production process is safe and non-toxic! At present, China's plastic TPE raw materials comply with FDA certification and LFGB standards. The test report includes ROHS, EN713, REACH, PAHS, and medical grade certification. It is widely used in adult products, baby products and tool handles, diving products, sports equipment, casters, massages Plastic products such as insoles, ice boxes, doll toys, luggage accessories, electric cables, auto parts, stationery, environmental protection films, elastic tubes, seals, etc.
　　 Two, the characteristics of PP material and the scope of use:
　　 Polypropylene material is polypropylene, a kind of plastic. It is a high-density, side-chain-free, highly crystalline linear polymer with excellent comprehensive properties! Mainly use household water bottles, buckets, plastic bags, fast food boxes, and beverage water bottles!
What are the characteristics of the PP material? Polypropylene is a non-toxic, odorless, and tasteless milky white highly crystalline polymer with a density of only 0.90--"0.91g/cm3, which is one of the lightest varieties of all plastics at present. The chemical stability of polypropylene is very good. In addition to being attacked by concentrated sulfuric acid and nitric acid, the chemical reagents of polypropylene are also relatively stable. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften and expand polypropylene. At the same time, the chemical stability of polypropylene increases with the increase in crystallinity, so polypropylene is suitable. It is good to make various chemical pipes and fittings with good anti-corrosion effect.
　　 3. Which TPE or PP material is safe?
　　From the perspective of environmental protection, polypropylene materials are non-toxic, but TPE meets food-grade standards, so TPE is safer than PP materials, and TPE will become one of the preferred raw materials for the plastics industry in the future. However, despite the high safety of TPE materials, the cost is naturally higher than that of PP. It is recommended that material buyers can choose these two materials according to the production and finished product characteristics of the product application, product consumption capacity and profit!
The above is all about the injection molding process of TPE and TPR materials. Various signs indicate that TPE/TPR is an environmentally friendly and non-toxic new material, which is popular with daily necessities, sports equipment, luggage handles, toy dolls, tool handles, soft materials, and smart homes. It has a wide range of applications; if you want to know more TPE/TPR material consulting information, you can follow our official website of Dongguan Mier Plastic Materials Co., Ltd.!
