Expanded Polypropylene (EPP) Exceptional Performance
Thermal Insulation Expanded Polypropylene (EPP)
- Expanded Polypropylene (EPP) has a standard R-Value of 4.0/inch of thickness. This meets insulation requirements for food service, heating and cooling, along with cold chain solutions.
Vibration Dampening Expanded Polypropylene (EPP)
- Good vibration dampening and even isolation can be readily achieved with Expanded Polypropylene (EPP) materials. This is highly application specific engineered on an ad hoc basis.
Reduction and Savings Expanded Polypropylene (EPP)
- Due to its lightweight particles, Expanded Polypropylene (EPP) solutions remove weight from component housings by replacing the mounting surfaces. Expanded Polypropylene (EPP) provides excellent fastening and mounting capabilities thus reducing assembly times and number of components. Seat assemblies in automobiles have reduced the weight by over 15 lbs for example.
Porous Expanded Polypropylene (PEPP) Sound Solutions
- Porous Expanded Polypropylene (PEPP) provides both absorption and transmission reductions in sound. By replacing metal housings in HVAC devices, Porous Expanded Polypropylene (PEPP) becomes the noise suppressor of choice.
Expanded Polypropylene (EPP) Chemical Resistant Properties:
- Very good chemical resistance overall, with resiliency against acids and alkalines, solvents, grease, oil, etc. A comprehensive guide to chemical resistance is published and available.
Expanded Polypropylene (EPP) Ultraviolet Radiation Resistance:
- Good UV resistance for most applications. Long-term exposure primarily affects surface color while some embrittlement, chalking and crazing can occur depending on exposure levels and durations. Data is published and available
Expanded Polypropylene (EPP) Humidity and Water Resistance:
- Good resistance to humidity and water exposure. Typical water absorption is 0.1% to 0.3% by volume after 24 hours submersion and 0.6% after 1 week. See property data for more detail.
