All kinds of inflatable products on the market now, including tents, amusement facilities, emergency rescue equipment, event props, etc., whether inflatable products or air-tight products are made of PVC and PVC mesh fabric. Today, I will briefly introduce you to PVC and PVC mesh fabric.

PVC is polyvinyl chloride, English abbreviation PVC (Polyvinyl chloride), is vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxides, azo compounds, and other initiators; or by free radical polymerization under the action of light and heat The polymer formed by the reaction mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. Its material is an amorphous material.

In practical use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents, and other additives. According to the different scopes of application, PVC can be divided into general PVC resin, high degree of polymerization PVC resin, and cross-linked PVC resin. PVC is very resistant to oxidizing agents, reducing agents, and strong acids.

The PVC sandwich mesh is made of two layers of PVC calendered film with a layer of high-strength polyester or nylon in the middle, which is heated and pressurized. Double strong, with non-flammability, high strength, cold and high-temperature resistance, and excellent geometric stability. The thickness varies from 0.45 to 1.8cm, which can be used according to actual needs.

The PVC mesh fabric with a thickness of 0.45 is used in the shape of the product or the surrounding guardrail fence; and the main load-bearing position of the product, the front tread position, the overall part of the slide, the overpass, etc., our national standard is that the sewing product must use more than 0.55, a certain Some countries need 0.6; high-temperature heat sealing products need more than 0.6.
