The above values are not intended for use in preparing specifications.
Heat resistance additives need to be added to meet the requirements of heat resistance.
Features:
This series features exceptional resistance to oils and solvents, characterized by low compression set, superior thermal stability, and high resilience.
Applications:
Optimized for both injection and compression molding, it achieves robust adhesion to metal, aramid, and various substrates when used with a specific primer.
Processing Advice:
It is recommended to use 0.4 ~ 0.7 phr. 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane(DBPH).
The customer shall decide the optimum curing temperature and time according to the product dimensions and curing methods.
Package &Storage:
Packed in plastic bags placed into reinforced cardboard boxes. Each box contains 2 bags with 10kg per bag.
Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. This product has cold-flow characteristics, should avoid bag breakage in the process of transportation and usage, shelf life is 12 months from the date of production. It is shipped as non-hazardous substance.
Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
