Applicability of plastic elbow products
Edit:Yuyao Longguo Extrusion Factory   UpDate:2017-04-14

the plastic products are widely used, large downstream industries provide a strong bend to the development of China's plastic products industry The support. With the "revitalization of the petrochemical industry planning rules," the introduction of China's plastic pipe products industry ushered in a new development opportunities. China's plastic products market demand is mainly concentrated in agricultural plastic products, packaging plastic products, building plastic products, industrial transport and engineering plastics products, and several other aspects. It has a very superior performance:

1, light weight

plastic elbow is a lighter material, the relative density distribution between 0.90-2.2. Obviously, can the plastic float on the water? In particular, foam plastic, due to microporous, lighter texture, the relative density of only 0.01. This feature allows the plastic to be used in products that require weight reduction.

2, excellent chemical stability

The vast majority of plastic on the acid, alkali and other chemicals have good corrosion resistance. In particular, commonly known as the plastic king of polytetrafluoroethylene (F4), its chemical stability even better than gold, on the "aqua regia" cook for a dozen hours will not deteriorate. Because F4 has excellent chemical stability, is the ideal corrosion-resistant materials. Such as F4 can be used as a corrosive and viscous liquid pipeline material.

3, excellent electrical insulation performance

Ordinary plastic elbow is a bad conductor of electricity, the surface resistance, volume resistance is large, with figures that can reach 109 to 1018 ohms The The breakdown voltage is large and the dielectric loss tangent is small. Therefore, the plastic industry in the electronics industry and the machinery industry has a wide range of applications. Such as plastic insulated control cables. In general, the thermal conductivity of plastic elbow is relatively low, the equivalent of steel 1/75 (3), the heat of the bad conductor, with muffler, shock absorption

-1/225, the pores of the foam.

5, the mechanical strength of the wide distribution and high specific strength

Some plastic elbow hard as stone, steel, some soft as paper, leather; from plastic hardness, Tensile strength, elongation and impact strength and other mechanical properties to see a wide range of distribution, there is a great use of choice. Due to the small proportion of plastic, high strength, which has a high specific strength. Compared with other materials, plastic pipe also has obvious shortcomings, such as easy to burn, stiffness, such as metal is high, resistance to aging is poor, not heat and so on.
