PORON® ShockPad Foam — 0.10 mm (4 mil) is an ultra-thin cellular polyurethane foam engineered specifically for impact protection in compact consumer electronics, where thinning device profiles leave displays, printed wiring boards, and other components with minimal available clearance for protective materials. Supplied on a release PET liner to facilitate precision converting and assembly, the 0.10 mm grade is suited for applications where even the 0.15 mm grade cannot fit.
Per TDS comparative performance data, PORON® ShockPad material outperforms competing ultra-thin foam materials by up to seven times in impact absorption testing. The 0.10 mm grade delivers a compression force deflection of 217 kPa (31.5 psi) at 25% deflection and a typical compression set of 4.3% at 70°C (158°F). The release PET liner has a breaking strength of ≥ 150 MPa MD/TD, an elongation of ≥ 200% MD/TD, and a heat shrink rate of 0.6–0.8% MD/TD; it is removed prior to final assembly.
What differentiates PORON® ShockPad 0.10 mm from the 0.15 mm grade?
The 0.10 mm (4 mil) grade is the thinner of the two ShockPad grades, delivering a higher compression force deflection of 217 kPa (31.5 psi) versus 141 kPa (20.5 psi) for the 0.15 mm grade, making it suited for the most space-constrained assemblies where even the 0.15 mm grade cannot be accommodated.
Why is compression set critical for an ultra-thin impact protection foam?
Compression set measures permanent deformation after repeated loading. A typical compression set of 4.3% at 70°C (158°F) means the 0.10 mm grade retains its original thickness and impact-absorbing capability throughout the service life of the device, even after repeated compression cycles.
What is the thickness and tolerance for PORON® ShockPad 0.10 mm?
The foam thickness is 0.10 mm (4 mil) with a tolerance of ± 0.025 mm (1 mil). The release PET liner ranges from 0.051 to 0.053 mm (2.01–2.09 mil) in thickness and is removed prior to final assembly.
Is PORON® ShockPad 0.10 mm suitable for regulated environments?
No compliance standards are specified on the manufacturer's TDS for this material. Suitability for regulated environments should be evaluated based on application-specific requirements.
How should PORON® ShockPad 0.10 mm be specified?
Specify grade (PORON® ShockPad), foam thickness (0.10 mm), dimensional tolerances, and finished format. Note that the release PET liner is removed prior to final assembly.
