Sumitomo Bakelite SUMILITERESIN® PR-NR-1 FI Flake phenolic resin
Categories:	Polymer; Thermoset; Phenolic
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. Information provided by Sumitomo Bakelite High Performance Plastics (sbhpp)
