Thermoplastic Elastomer ( TPE - SEBS / SBS COMPOUND) , sometimes referred to as Thermoplastic Rubbers are a class of a Plastic and a Rubber which consist of materials with both Thermoplastic and Elastomeric Properties. Thermoplastics are in contrast relatively easy to use in manufacturing, for example by Injection Moulding or Extrusion process. Thermoplastic Elastomers shows advantages typical of both Rubbery materials and Plastic Materials. The benefits of using Thermoplastic Elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. TPEs have outstanding thermal properties and material stability when exposed to a broad range of temperatures and non-polar materials. TPEs consume less energy to produce, can be coloured easily by most dyes, and allow economical quality control.
Thermoplastic Olefins (TPO) or Olefinic Thermoplastic Elastomers refer to Polymer / Filler blends usually consisting of some fraction of a Thermoplastic, an Elastomer or Rubber, and usually a filler. Thermoplastics may include Polypropylene (PP), Polyethylene (PE), Block Copolymer Polypropylene (BCPP), and others. Common fillers include, though are not restricted to talc, fibreglass, carbon fibre. Common Elastomers include ethylene propylene rubber (EPR), EPDM (EP-diene rubber), ethylene-octane (EO), ethyl enzene (EB), and styrene ethylene butadiene styrene (SEBS). Outdoor applications such as roofing frequently contain TPO because it does not degrade under solar UV radiation, a common problem with nylons. TPO is used extensively in the automotive industry. TPO is easily processed by injection moulding, profile extrusion, and thermoforming.
Speciality Compound has high comprehensive properties, Good Chemical Resistance, Thermal Stability, Low Water Absorption, Low Specific Gravity, Good Insulation. Well suited for processing using Injection, Extrusion and blow-moulding. Modification of Polymers by compounding with Talc Filled, Mineral Filled, Glass Filled and Flame Retardant produces a substantial change in the properties of the base material and gives to compositions based on the following properties like Mechanical, Appearances, Chemical Resistance and Excellent Moulding Properties. Application are in extensive range in Electronic appliances, Electrical accessories, Lighting Equipment’s, Connectors, Automotive, Cooling Fan, Battery Cases also in household equipment.
Master batch (MB) is a solid additive for plastic used for colouring plastics (colour master batch) or imparting other properties to plastics (additive master batch). Master batch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Master batch allows the processor to colour raw polymer economically during the plastics manufacturing process.
