Good Rigidity CPVC Compound for Transparent Fitting/Heat-Resistant Industrial Plates/Sheets

This may be related to the processing temperature, screw shear conditions, stabiliser system, the amount of processing aids used, and the CPVC resin grade. It is recommended to readjust the plasticisation temperature and the proportion of processing aids according to the resin grade, and to check the uniformity of mixing.

This is usually related to excessively high processing temperatures, excessive residence time, insufficient thermal stabilisers, or localised overheating. It is recommended to check the equipment's temperature control, material residence time and the stabiliser system.

This may be related to the type and dosage of impact modifiers, the grade of CPVC resin, the degree of plasticisation, and the formulation ratios. Impact modification systems such as CPE and MBS can be optimised according to product requirements. Please contact us for assistance in selecting a more suitable CPVC resin.

CPVC has relatively high processing temperature requirements, whilst its thermal stability window is relatively limited. If the temperature is too low, insufficient plasticisation may occur; if it is too high, the resin may degrade. Therefore, during production, it is necessary to maintain plasticisation, flow properties and thermal stability within an appropriate range.

Yes, we can provide samples upon customer request for formulation development, production testing and product performance verification, to help customers confirm the suitability of the material prior to bulk purchase.
