Temperature Resistance

The most important factors concerning the resistance to temperature of plastics are: the duration of exposure to the heat source and the presence of applied forces. In fact, softening is the greatest risk in the presence of heat. In this phase, if a force (locking) is applied it is easier to break the bond between the plastic and the moulded-in metal inserts. Notwithstanding the fact that the inserts are designed for strong adhesion to the plastic material, if certain temperatures are exceeded the use of the part is affected.
