Plastic molding

Many plastic molding applications require precise temperature control. Localized heating with electric heating elements often does not provide the user with enough precision to guarantee product quality. Therefore, the use of heat transfer fluids has become the standard in the industry. Reservoirs, molding machines, and extruders can all be heated to exact temperatures by circulating heat transfer fluid at a controlled rate. The elevated temperatures required and potential problems with corrosion usually prohibit the use of steam because of the relatively small flow passages within the equipment used in the industry. Since Eastman Therminol® heat transfer fluids are noncorrosive and thermally stable when used within their recommended operating temperature ranges, they can be used for nearly all plastic molding applications.
