ABS: 102.3 o C; PVC: 92 o C; PE: 127.3 o C; PP: 152.2 o C Melting Point of Polypropylene - The melting point of polypropylene occurs at a range. CHLORINATED POLYVINYL CHLORIDE (CPVC) PROPERTIES CPVC shares most of the features and properties of its close relative, PVC. The melting point of PVC is normally 212 0 C. Glass transition temperature is about 81 0 C. Glass transition temperature is the temperature at which the polymer transits from a hard glassy state to a rubbery state upon the increasing of temperature. PVC may be used to temperatures of 140°F (60°C) and is readily available in sheets, rods, and tubing. The melting point for average, commercial, low density polyethylene is typically 105 to 115 °C (221 to 239 °F). CPVC offers some benefits over PVC, but at a slightly higher price point. In best case it would be transparent. PVC may be cemented, welded, machined, bent and shaped readily. The melting point changes from approximately 160 to above 300°C.

For applications requiring temperatures above that, CPVC (chlorinated polyvinyl chloride) is recommended. Homopolymer: 0.904 – 0.908 g/cm 3 This feature makes it a suitable option for lightweight\weight saving applications. » Visit Polymer Additives Selector for all Plasticizer Grades! Most LDPE and HDPE grades have excellent chemical resistance and do not dissolve at room temperature because of their crystallinity. third reference: The effect of polymerization temperature on melting point is even more striking. on lowering the polymerization temperature from 125 to -80°C. PVC has a peak temperature threshold of 140° Fahrenheit. PVC can be made either as a flexible plastic or a rigid plastic by the means of additives. PVC Schedule 40 DWV Pipe & Fittings. PVC Pipe Uses. The second reference puts it at 182C. ABS: 104 - 106 o C; PVC: 54 - 80 o C; HDPE: 43 - 49 o C; LDPE: 32 - 41 o C; PP: 57 - 64 o C; Vicat Softening Temperature - is the temperature where a needle shaped penetrator sinks into a test piece a specified depth when a specified vertical load (1 kg) is applied. This system is intended for pressure applications where the operating temperature will not exceed 140 degree Fahrenheit. Expanded PVC is widely used for: Printable—digital and screen Signage, point-of-purchase (POP) displays Exhibits and kiosks Photo mounting Display boards Wood replacement Prototypes Shelves and fixtures Performance characteristics: Rigid, lightweight but durable Easy to machine, fabricate, and thermoform Die-cuttable PVC is also self-extinguishing per UL flammability tests. ... Melting point −50°C: Boiling point: 250 - 257°C at 0.5 kPa: Thermosoftening plastics melt when they are heated. Hi all, I am looking for a Commercial polymer with a melting point of about 50°C (120F) and mechanical properties comparable to PP or PE. It is similar to the material used in biodegradable plastic packaging and melts at between 180 and 200 degrees C… Polyvinyl chloride, according to wikipedia, melts at 100-260C. ASTM D 1785: Specification for poly (vinyl chloride) (PVC) plastic pipe, Schedule 40, 80, and 120 Scope: This specification covers PVC pipe in Schedule 40,80, and 120 for pressure applications. Homopolymer: 160 - 165°C; Copolymer: 135 - 159°C; Density of Polypropylene - PP is one of the lightest polymers among all commodity plastics. This means that they can be recycled , which involves melting them before making a new product. Approved PVC pipe uses depend on the application and local building codes. Plasticized PVC (or flexible PVC) finds applications in automotive interior trim, cables, PVC films, flooring, roofing and wall coverings, etc.
