Shenzhen Dazhan Tenology Industry Co.,Ltd tell you that the traffic facilities products usually have warning column, road cones, pillar, column isolation, beads and so on a series of material with polyethylene (PE), polyurethane (PU), ethylene/vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), small make up to you now with the difference and application of these materials.
1:PE is odorless, non-toxic, hand-like wax, with excellent low temperature resistance, chemical stability and insulation, main USES: 1.2. High pressure polyethylene, more than half of which is used for film products, followed by pipes, injection moulding products, wire wrap and so on;3. Uhpe can be used as engineering plastics due to its excellent comprehensive performance.
2. Shenzhen Dazhan Tenology Industry Co.,Ltd introduces that PU can obtain different physical properties such as density, elasticity and rigidity by simply modifying the formula.At present, a large number of replacement glass fiber insulation materials, wood, traditional rubber products.
3. EVA has the characteristics of bright appearance, folding resistance, wear-resisting, corrosion resistance, low temperature resistance and non-channeling color, which is widely used in the field of foaming shoe materials, functional shed film, packaging film, hot melt adhesive, wire and cable and toys.
Shenzhen Dazhan Tenology Industry Co.,Ltd tells us that PVC has good processing performance, low manufacturing cost, corrosion resistance, climate resistance, insulation and other good features.In practice, stabilizers, lubricants, auxiliary processing agents, color materials, anti - shock agents and other additives are often added.However, it can be corroded by concentrated oxidizing acids such as sulfuric acid and nitric acid and is not suitable for contact with aromatic and chlorinated hydrocarbons
