How to improve the resilience of PVC plastic hose
Mar 05, 2022
How to call a y-quality PVC hose, its requirements must at least meet these basic properties: high pressure resistance, aging resistance, wear resistance, softness, tenacity, drag resistance, vibration resistance, cold resistance, corrosion resistance, acid and alkali resistance, flame retardant, the product is not soft when heated, light and durable, etc.
The PVC hose produced by most plastic steel wire hose manufacturers can't achieve these basic properties at all. Instead, there will be various problems, such as bursting due to high temperature resistance of the oven, insufficient tensile test of the oven, etc. of course, in addition to the production process, temperature control, extrusion speed, etc., it is more important to select the right raw materials. The main material of PVC hose is polyvinyl chloride (PVC) resin, and PVC itself has no elastic and flexible chain structure, Therefore, its low-temperature resistance is poor. As an elastomer, powdered nitrile rubber nbr-p8300 has high compatibility with PVC and forms an "island" structure when blending with PVC. This uniform mixing system can effectively improve the flexibility of PVC and its low-temperature resistance. Due to its fine particles, good dispersion and fluidity, the soft particles of rubber particle elastomer are evenly distributed in the mixed materials, so as to reduce the wear and tear of PVC soft products
