This document Flexible PVC WILLIAM COAKER Origins Polyvinyl chloride (PVC) homopolymer is a semi-crystalline polymer with a relatively high room temperature tensile modulus of to MPa (– · psi), depending on formulation) that can be lowered by plasticizing entities to produce semi-rigid and flexible Scope of the Handbook This book will be mainly concerned with the extrusion of thermoplastic prod-ucts because of their importance in extrusion processes. Many of these have turned out to be commercially useful and cost Many of the fundamental technology discoveries related to PVC were made in the ’s through the ’s. This is due to (a) the wide variety of PVC resin types available (varying in molecular weight and distribution, homo-, co-, and terpolymers, particle size and distribution, morphology, ,  · The PVC pipe industry has matured with guidance from standards bodies and trade associations to offer a reliable and durable piping product. Design CriteriaPipe Loading, P y The loading on a buried pipe is comprised of two elements, dead load and live load. (to mm) greater than the pipe OD forin. (mm) forandin. The document is a book about PVC (polyvinyl chloride) containing information on its chemistry, history, manufacturing, and uses As processing technology developed, unplasticized (rigid) PVC began expan-sion into replacement of metal, glass, and wood, a trend that continues and which now consumes the greatest part of PVC usage. By polymer matrix, PVC compounds account for% of additives by volume. (mm) and larger sizes. Polyolefins make up% and styrenics 5%, while the other polymers make up the remaining%.

The acceptance of PVC is based on its performance-to-cost ratio. Thermoplastics are by far the largest group of plastic materials extruded; approximately% of all plastics pass through an extruder. The dead load is the pressure exerted on the pipe by the weight of the soil or some stationary mass above the pipe PVC°C Thermal Rating The current carrying capacities for thermoplastic cables, including flexible cords used as fixed wiring, insulated with V and VHT PVC compounds have been based on a conductor operating temperature of°C (refer AS/NZS TableNote 2)The HandbookCurrent Ratings Flexible Cable Cord Minimum width recommendations arein.
