Rigid foam water absorption test

Rigid foam plastics refer to foam plastics that have no flexibility, high compression hardness, can deform when the stress reaches a certain value, and cannot return to their original shape after the stress is relieved. They can be used as thermal insulation materials, sandwich materials, packaging materials, sound insulation and earthquake-proof materials, building materials, etc. The water absorption test of rigid foam plastics can determine the water absorption rate of rigid foam plastics by measuring the buoyancy of the sample after being immersed 50 mm in water for 96 hours.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various rigid foam plastics and provides professional water absorption testing services for rigid foam plastics.

Rigid foam plastics mainly include: polystyrene foam, phenolic foam, polycarbonate foam, epoxy foam, rigid polyvinyl chloride, most polyolefin foams and some polyurethane foams.

Determines the water absorption rate of a material by measuring the buoyancy of a sample soaked in distilled water for a certain period of time. The soaking liquid is distilled water that has been placed for at least 48 hours after distillation.
