PP 1102LP﹂L(zhǎng)ong-term supply of TPU, but also improve the safety performance of the bumper. In addition, there are high moisture permeability, TPU, conductive TPU, and there has been a TPU dedicated to the body, tapes, safety glass and so on. The difference between 6.TPE and TPE - PVC thermoplastic elastomer is a kind of new material with high elasticity, high strength and high resilience. TPE material has soft touch, good weather resistance and no plasticizer. It is a kind of environmental protection non-toxic material. The price is between 2.5 - 50 thousand / ton, and it is widely used in daily necessities. PVC - polyvinyl chloride is a poisonous chlorinated resin. When processing adds the plasticizer, the plasticizer content is bigger, the material is softer, widely used in the building material, the artificial leather, the price is between 0.8 - 12 thousand yuan / ton. PVC plastic products at higher temperatures, such as
about 50 degrees Celsius will slowly decompose hydrogen chloride gas, this gas harmful to human body. Compared with PVC, TPE is more resistant to high temperature and low temperature, and has better elasticity. In recent years, environmental protection has become more and more popular. Therefore, in many fields, energy-saving and environmental protection thermoplastic elastomer TPE has begun to replace PVC. TPU, 134/F, TPU, 201/F, TPU, 315F, TPU, 616/1, TPU, 618/1, TPU, 975U, TPU, V2580, TPU, V2804
TPE advantages 1. can be processed by a general thermoplastic forming machine without the need for special processing equipment. 2., production efficiency has increased substantially. It can be directly vulcanized with rubber injection molding machine. The time is shortened from 20min to 1min. Because of the short curing time, the extruder can be directly vulcanized, and the production efficiency has been greatly improved. 3. easy to recycle and reduce costs. Waste generated in the production process (escape flash, out of waste plastic) and Zui end the waste, can return to re-use; after simple regeneration recycling used TPE old product, reduce environmental pollution, expanding sources of renewable resources. 4. energy saving. Most thermoplastic elastomers do not require vulcanization or vulcanization time is very short, it can effectively save energy. To high-pressure hose production energy consumption as an example: rubber for 188MJ, TPE for 144MJ, energy saving can be more than 25%. 5., a wider range of applications.
PC /ABS, such as excellent mechanical properties of ABS and PC, easy processing characteristics and thermal stability. The ratio of the two will affect the thermal stability of PC / / /ABS materials. ABS plastic characteristics: 1, good comprehensive performance, high impact strength, chemical stability, good electrical properties,.PC /ABS2, and 372 organic glass frit is good, made of double color plastic parts, and chromium plating surface, spray paint processing,.3 have a high impact, high heat resistance, flame retardant, and enhance transparency and level. 4, liquidity than HIPS less than PMMA, PC, etc., good flexibility. 5, the mechanical properties of the outstanding balance 6, low temperature also has high impact strength 7, indoor UV stability of 8, high heat deformation temperature (80 to 125 DEG C) 9, flame resistant (UL945VB) 10, 11 color range, easy injection and extrusion, blow molding processing 12, good 13, electroplating the general density in 1.05-1.20 identification of 1 new methods: using ethyl acetate wipe, ABS not HIPS be silk, silk, but only refers to pure.
To improve the performance of EMA copolymer Zui note (with LDPE homopolymer phase comparison) include: VEKA (Vicat) softening temperature from 194 DEG F decreased to 138 DEG F; flexural modulus decrease; resistance to environmental performance fracture significantly improved; enhanced dielectric properties. This material has a good resistance to most chemicals, but is not designed to be used as a continuous infusion in you, Ji, and nitric acid. 3 processing uses standard LDPE film extrusion production line, at
about 325 degrees F melting temperature, it is easy to EMAC processing into blown film. Blown film has very high impact strength, and it is easy to fuse with traditional hot-melt equipment or radio frequency method (RF).
EVA resins have a wide range of uses. In general, the vinyl content is below 5% EVA, its main products are film, wire and cable, LDPE modifier, adhesive; vinyl acetate content in 5%~10% EVA products for elastic film; vinyl acetate content in 20~28% EVA, mainly used for hot melt adhesives and coating products; vinyl acetate content in 5%~45% the main products (including film, agricultural film and sheet), injection molding, molding products, foam products, hot melt adhesive etc..
EEA when the content of ethyl acrylate (EA) increases, the copolymer will become more tough, softer and more flexible. The polarity of the resin with high ethyl acrylate increases the ability of the surface to absorb ink and has the adhesive property. With the increase of EA content, the density and softness of copolymer increase. EEA has good low temperature performance and softness, good thermal stability in processing, large packing capacity, good resistance to bending and cracking, environmental stress cracking, and greater elasticity. The cross
linking of EEA with organic peroxide can improve heat resistance, creep resistance and solvent resistance. When the content of ethyl acrylate (EA) increased, the upper limit temperature of copolymer decreased slightly, and the transparency decreased.
