PVC is the growth rate of 4% of the production and application worldwide. PVC growth in Southeast Asia is particularly significant, thanks to the Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce the material of the material properties of ABS (acrylonitrile - butadiene - styrene) ABS is used for conveying drinking water, mud and chemicals. The most commonly used DWV (drain waste exhaust) applications. Unplasticized polyvinyl chloride (UPVC) and CPVC (chlorinated polyvinyl chloride after) having the entire operating temperature range within UPVC excellent chemical resistance, with a wide range of operating pressure belt. Due to the nature of long-term high-intensity, stiffness and cost-effectiveness, UPVC systems account for a large proportion of the plastic pipe installation. CPVC is resistant to many acids, bases, salts, paraffins, halogen and alcohols. This is not an anti-solvent, aromatic hydrocarbons and some chlorinated hydrocarbons. PP (polypropylene) Polypropylene is suitable for use in food, drinking water and ultra pure waters pvc tubes offer, as well as in the pharmaceutical, chemical and other industries. PE (polyethylene) polyethylene has been used successfully for many years drinking water and wastewater, hazardous waste, and safe transportation of compressed gas. PVC resin is a polar non-crystalline polymers, density: 1.380 g / cm pvc pipe manufacturers, glass transition temperature: 87 ℃, so the differential thermal stability, easy processing. Can not be used directly, must be modified mixed, add the relevant additives and fillers can be used. And because of different additives and added to the relevant type and filler fraction, which determines the material properties and the requirements of PVC prepared is not the same. We usually call it PVC formulations, strictly speaking is modified PVC formulations, but only after a modification to use PVC. This category is often classified as a polymer modified materials. Studies of polymer materials modified plastics primarily focus on high performance general-purpose, single-component materials to the multi-component composite material change (alloys, blends, composites), giving the material functions, optimization of performance and price and so on. Modified method is mainly chemical modification, filling modification, enhancement modification, blending modification and nano-composite modified. The basic principle is modified by providing material additives function or enhance certain properties. Therefore pvc pipe, PVC formulation technology to compete, decided a factory technology and production capacity to compete. PVC resin is a polar non-crystalline polymers, density: 1.380 g / cm, glass transition temperature: 87 ℃, and therefore poor thermal stability, difficult processing. Can not be used directly, must be modified mixed, add the relevant additives and fillers can be used. And because of different additives and added to the relevant type and filler fraction, which determines the material properties and the requirements of PVC prepared is not the same.

The basic principle is modified by providing material additives function or enhance certain properties. Therefore, compete with PVC formulation technology, determines a plant technology and production capacity to compete. pvc pipe manufacturers, sea Widex (certified), pvc pipe provided by Qingdao Rubber Material Co., Widex.
