This strength is possible because HDPE polymers have little or no branching. The "little or no branching" characteristic results in significantly stronger intermolecular forces that make HDPE harder and more resistant to temperatures of up to 120  0 C (248  0 F) for short periods. This property also makes HDPE resistant to a lot of acids, caustics
