At present, the green guardrail industry has formed a number of large enterprises as the main body.
In the next few years, PVC guardrail industry will gradually enter a quiet development period, the market gradually revealed eight major development trends to form a large enterprise-led, small and medium-sized enterprises as a secondary market structure. Lawn guardrail using special formulations and special ultraviolet absorbent, do not fade, not yellow, not peeling, not cracking, not moth, guardrail cavity with a steel pipe to enhance, with sufficient strength and impact resistance, so that PVC guardrail both the strength of steel and PVC beautiful.
PVC Steel guardrail without paint and maintenance, product long new not old, exempt you from the maintenance of fatigue and cost, low comprehensive cost, service life of more than 25 years. Lawn guardrail material is a kind of plastic decorative materials is the abbreviation of PVC material, PVC resin is made of vinyl chloride monomer polymerization of thermoplastic polymers. PVC resin is the main raw material, add appropriate anti-aging agent, modifier, etc., by mixing, calendering, vacuum blister and other technology.
PVC is amorphous polymer with crystalline 5%--10% (melting point 175 degrees). The physical energy of the molecular weight crystallinity softening point of PVC changes with the polymerization conditions. Lawn guardrail to PVC resin as the base, and stabilizer, plasticizer, filler, coloring agent and modifier, such as a variety of additives through the plastic molding process into PVC resin plastic. PVC material has the characteristics of light weight, heat insulation, damp-proof and flame retardant construction. The specification color pattern is numerous, the extremely rich adornment is widely used in the production and the life.
such as PVC hose PVC plastic doors and windows, as well as PVC-containing plastic toy wire and cable.
