Xinda Plastic Machinery Co., Ltd. self-developed the carpet back coating TPR PVC production machine, the main raw material used for the TPR or TPE, PVC can also be used to reduce production costs, but the properties of the plastic is TPR / TPE thermoplastic is more suitable for carpets film.
TPR / TPE thermoplastic elastomer, also known as thermoplastic rubber, thermoplastic rubber and is a characteristic of both, showing a high rubber elasticity at room temperature, high temperature plastics molding but also polymer materials. It is following the natural rubber, synthetic rubber, after the so-called third-generation rubber, referred to as TPE or TPR. The structural characteristics of the thermoplastic elastomeric polymer chain is composed of the chemical composition of different resins segment (hard segment) and a rubber segment (soft segment) composition. Both rubber and thermoplastic properties characteristic of the rubber industry production processes to shorten the 1/4, energy savings of 25% to 40% and improve efficiency 10 to 20 times, and again called the Rubber Industry materials and technology revolution.
TPE, TPR properties:
- have a good touch, adjustable physical properties, with the environmental requirements.
2. Non-toxic, odorless, no harm
3. Excellent heat resistance, low temperature resistance (-60); resistance to general chemical resistance and electrical insulating properties
4. That is not curing characteristics of vulcanized rubber
5. suitable for injection molding or extrusion molding machine
6. scrap, excess material can be completely recycled and reduce costs (hundred percent recovery)
7. The processing time is short, high production efficiency
8. excellent weather resistance, ozone, ultraviolet light, a good arc tolerance
9. The low density, unit weight higher utilization
10. Coloring outstanding performance: the pigment dispersed evenly, no flow marks, do not fade
11. The excellent electrical properties: volume resistivity: 10-10 ohm-cm, the breakdown voltage strength; high pressure up 39.3Mv / m
12. A second injection with PP, PE, HIPS, ABS, PC, PA and other materials firmly adhered.
13. Toughening, adding a certain proportion of the PP, PE, PS, ABS, PC, PA and other materials TPE / TPR to increase the toughness of the product, improve product performance and impact absorption, reduce product fragile, breakable situation. Good physical properties appearance of texture, feel gentle; easy to color, color uniformity, stability; properties adjustable to provide a broad creative space for product design; mechanical properties comparable vulcanized rubber, but not curing crosslinking; the hardness of a wide range, from SHORE-A 0 degrees to SHORE-D 70 degrees adjustable; excellent resistance to tensile properties, tensile strength of up to a dozen Mpa, elongation at break of up to more than ten times; long-term temperature can exceed 70 ℃, low temperature performance well, at -60 ℃ still maintain good flexibility; good electrical insulation resistance and voltage characteristics; outstanding slip resistance, abrasion resistance and weather resistance and the like.
