Phenolic resin 2201 is a low-free phenol thermosetting resin, featuring high bonding strength and low odor. It differs from the conventional 1101 model and is more suitable for environmentally friendly and high-precision processing scenarios. It is mainly used in rubber reinforcement, adhesives, mold manufacturing, and other fields. Using high-quality phenol and formaldehyde as raw materials, it is refined through an improved polycondensation process. It is a light yellow transparent solid with a mild odor and no obvious irritation. After curing, the structure is dense, and its toughness is superior to that of ordinary phenolic resin, meeting the processing needs of multiple industries such as rubber, machinery, and building materials.

Product advantages
The core advantages are low content of free phenols, mild odor, compliance with environmental protection processing requirements, and greater safety in use; extremely strong adhesive force, which can effectively enhance the bonding strength and structural stability of rubber and composite materials; a softening point higher than 1101, making it less likely to melt and lose during high-temperature processing, resulting in better processing stability; adjustable curing speed, suitable for various processing methods such as compression molding, pouring, and coating; resistant to wear, acid and alkali, and less likely to deform after curing, suitable for high-precision molds, high-end rubber reinforcement and other scenarios.
