UPVC materials have a specific gravity of only 1/10 of that of cast iron, which is easy to transport and reduce costs.

Superior chemical resistance: UPVC has excellent acid and alkali resistance, except for the strong acid-base or strong Oxidising agents atmaximun.

UPVC: Non-conductive: UPVC materials are not conductive, and are not subject to electrolysis, current corrosion, and should not require secondary processing.

Can not burn, does not support combustion, no fire concerns.

Easy installation and low cost: cutting and connecting are very simple. The practice of using PVC glue connection proves reliable and safe, easy to operate and low in cost.

Durable: It has excellent weather resistance and cannot be corroded by bacteria and fungi.

The resistance is small and the flow rate is high: the inner wall is smooth, the fluid fluidity loss is small, and the dirt is not easily attached to the smooth pipe wall, the maintenance is relatively simple, and the maintenance cost is low.

 Adaptation range of pvc transparent material: For airplanes with a flight speed greater than Mach 2.3, the windshield and canopy cover are subject to large aerodynamic heating, and transparent materials with higher heat distortion temperature, better toughness and stronger impact resistance are needed. Such as polycarbonate. Ordinary silicate glass is heat-resistant and wear-resistant, but it is brittle and fragile, so most of the aircraft use tempered glass that has been treated by physical or chemical methods. The tempered glass, oriented plexiglass or polycarbonate plastic is sandwiched between soft and sticky films to form a multi-layer composite transparent glass material, which is bulletproof and bird resistant, and is used as an anti-bird windshield for aircraft. The windshield and observation window of the manned spacecraft, space shuttle and artificial satellite adopt a double-layer composite structure, that is, high-heat silicate glass or quartz glass with high heat resistance as the thermal barrier layer, and the chemistry with high thermal stability and high strength Reinforced aluminosilicate glass as bearing layer
