Hanyao PVC coated fiberglass sleeve from China is a type of flexible hose made by weaving glass fiber yarn into a tubular substrate and then coating the outer layer with polyvinyl chloride (PVC) resin.Its base material is fiberglass, which provides the skeleton and gives the hose strength, heat resistance, and dimensional stability (no shrinkage, no stretching).Coated with polyvinyl chloride (PVC),which is a widely used general-purpose plastic used to protect glass fibers, provide flexibility, weather resistance, and a variety of colors.
The PVC coating makes it very flexible, easy to bend and install, and it maintains good elasticity even at low temperatures. This is one of its major advantages.Its core advantage is its low cost, with prices far lower than silicone and acrylic fiberglass sleeves, making it an ideal choice for cost-sensitive applications.However, its continuous operating temperature range is typically only -10°C to +70°C, and its short-term peak temperature generally does not exceed +100°C.
It must never be used in high-temperature applications, otherwise it will soften, deform, or even melt.

1.This PVC coated fiberglass sleeve’s continuous operating temperature range is typically from -10°C to +70°C.
2.The PVC coating makes it very flexible, easy to bend and install, and maintains good elasticity even at low temperatures.
3.PVC itself is impermeable to water, so this type of hose has excellent waterproof and moisture-proof properties.
4.With a price significantly lower than silicone and acrylate fiberglass hoses, it is an ideal choice for cost-sensitive applications.
5.Due to its low cost and excellent liquid and moisture resistance, PVC fiberglass hoses are widely used in medium and low temperature applications where there is no risk of high temperature.
