Polymeric Vinyl Product Description
May 24, 2017

Polymeric Vinyl is a crystalline thermoplastic resin. Their chemical structure, molecular weight, degree of polymerization and other properties are largely dependent on the polymerization process used. The aggregation method determines the type and degree of branching. The degree of crystallinity depends on the degree of the molecular chain and the thermal history it experiences.

Polymeric Vinyl is very sensitive to environmental stress (chemical and mechanical effects), heat aging resistance is worse than the chemical structure of the polymer and processing strips. Polymeric Vinyl can be processed by general thermoplastics molding methods (see plastic processing). It is widely used in the manufacture of film, packaging materials, containers, pipes, monofilament, wire and cable, daily necessities, etc., and can be used as high-frequency insulation materials such as TV and radar. With the development of petrochemical industry, Polymeric Vinyl production has been developing rapidly, the output of plastic production accounts for about 1 / 4. In 1983 the world's total Polymeric Vinyl production capacity of 24.65Mt, under construction capacity of 3.16Mt. The latest statistics in 2011, the global production capacity of 96Mt, Polymeric Vinyl production trends show that production and consumption gradually transferred to the Asian region, China has become the most important consumer market.

In the nuclear physics, astrophysics, reactor operation using Polymeric Vinyl as a diffusing agent to measure neutrons. On the nuclear physics research made its own contribution.

Polymeric Vinyl (PE) plastic, we often mention the bag is Polymeric Vinyl (PE). Polymeric Vinyl is the most simple polymer, but also the most widely used polymer materials. It is made by repeating the -CH2-unit. Polymeric Vinyl is formed by addition polymerization of ethylene (CH2 = CH2).

The performance of Polymeric Vinyl depends on its polymerization. Ziegler-Natta polymerization was carried out under medium pressure (15-30 atm) organic compound catalytic conditions for high density Polymeric Vinyl (HDPE). Under these conditions, the polymerized Polymeric Vinyl molecules are linear, and the molecular chain is very long, molecular weight up to several hundred thousand. If it is in the high pressure (100-300MPa), high temperature (190-210C), peroxide catalytic conditions free radical polymerization, is produced by low-density Polymeric Vinyl (LDPE), which is branched structure.
