Material Notes: SUMILITERESIN® PR-NR-1 FI is a cashew modified phenolic resin with a flake shape. It is generally applied for tire and rubber as reinforcement. It contains modified cashew nut shell oil and has a high molecular weight in order to obtain a higher modulus, increased toughness, and lower heat generation.

SUMILITERESIN® PR-NR-1 FI requires the addition of about 10% hexamine to thermoset properly.
