TPE adhesive PP material TPE adhesive PP
Both TPE and PP are raw materials for the manufacture of plastic products, but many material buyers may not understand the safety of TPE or PP materials? The quality of material purchases directly affects the sales profit of the finished product. As the standard of living improves, most consumers buy plastic products that take into account environmental protection and health issues. DeChuang Chemical explains to everybody which safety of TPE and PP material? The material characteristics of both are introduced.
One: What is TPE? TPE material properties and scope of application:
The full name of TPE is Thermopolistic Elastomer, a thermoplastic elastomer material. Thermoplastic means that it can be recycled and can be molded. TPE products have excellent coloring, environmental protection and non-toxic. It can be re-injection molding, bonded with PP, PE, PC, PS, ABS and other matrix materials, and can also be formed separately.

TPE is less heat-resistant than rubber and has a greater decline in physical properties as temperatures rise, thus limiting the scope of application. At the same time, the compression deformation, elastic recovery, and durability of rubber are relatively poor, 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. It has good UV resistance, weather resistance and high temperature, and is used outdoors for a long time. And ... TPE is also a complex of many thermoplastic elastomers(TPEE, TPA, TPO, TPV, TPU)!
TPE has the characteristics of safety and non-toxic, and environmental protection conforms to the Environmental Protection standards of European and American countries. A wide range of processing methods, such as injection molding, extrusion, pouring, blowing molding and other processing processes, comfortable texture, convenient surface, wide hardness range(0-100A), can be used repeatedly, the production process is safe and non-toxic! At present, TPE raw materials meet FDA certification and LFGB standards. Test reports include ROHS, EN713, REACH, PAHS, and medical level certification. They are widely used in adult products, baby products, and tool handles. Tools grips, diving supplies, sports equipment, casters, massage pads, ice boxes, doll toys, luggage accessories, utility cables, auto accessories, stationery, environmental protection films, elastic tubes, seals and other plastic products.
Second, the characteristics of the PP material and the range of use:
Polypropylene material is polypropylene, a kind of plastic, it is a high density, no side chain, high crystal linear polymer, with excellent comprehensive performance! Mainly use domestic kettle, bucket, plastic bag, fast food box, drink water bottle!
PPmaterial has what characteristics, polypropylene is non-toxic, odorless, tasteless milky white high crystal polymer, density is only 0. 90 -- "0. 91 g/cm3 is currently one of the lightest varieties of all plastics. Polypropylene has good chemical stability. The chemical reagent of polypropylene is relatively stable in addition to being eroded by concentrated sulfuric acid and nitric acid. However, low molecular weight fatty hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften and expand polypropylene. At the same time, the chemical stability of polypropylene increases with the increase of crystallinity, so polypropylene is suitable. Production of various chemical pipelines and accessories, good anti-corrosion effect.
Which of the TPE or PP materials is safe?
From an environmental perspective, 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 raw materials of choice for the future plastics industry. However, despite the high safety of TPE materials, the cost is naturally higher than PP. It is recommended that buyers of materials can select these two materials based on the production and finished product characteristics of the product application, product consumption capacity, and profit!
