Our high temperature sheet portfolio consists of products that offer significant retention of physical properties, dimensional stability, and excellent electrical characteristics that can be used at temperatures above 300°F (150°C).
- Excellent creep resistance
- Excellent chemical resistance
- In many cases, excellent wear resistance
- Ability to mix other performance enhancements
High Temperature Portfolio
ESP™, in conjunction with RTP Company, develops high temperature compounds to your specifications; providing flame retardant, wear resistant, conductive, structural reinforcement, and color modifications.
Characteristics of High Temperature Compounds:
- Strength and modulus decrease as the temperature increases
- Reinforcements increase short-term load carrying capabilities
- Polymeric impact modifies reduce both long- and short-term capabilities
- Thermal stabilizers increase long-term capabilities in some polymers
- Most other additives have little effect on thermal properties
High Temperature Resin Series:
|RTP Company Series Number||Resin System|
Glass Transition Temperature (Tg)
Temperature at which a material goes from a glossy state to a rubbery state. Key property changes include softening, reduction in density, and large drop in strength and modulus.
Continuous Use Temperature
Function of the thermal breakdown of the polymer. Difficult to increase by adjusting additives.
Heat Deflection Temperature (HDT)
Temperature at which a material will deflect a specified amount at a specified load. Good indicator of short term/low load thermal capabilities.
Melt Temperature (Semi-crystalline Resins Only)
Temperature at which the crystalline structure has enough energy to break down and allow for flow.
Properties are the same in all directions. In reference to dimensional effects due to temperature change, isotropic materials exhibit similar change in all directions.
Properties are not the same in all directions. In reference to dimensional effects due to temperature change, anisotropic materials exhibit less change in the flow and a greater change in transverse to flow directions.
