Phenolic resin 3102 is a high-toughness and high-temperature-resistant thermosetting resin. It differs from the conventional 1101 and 2201 models. It is mainly characterized by its excellent impact resistance and high temperature resistance, and is specifically used in scenarios with high requirements for mechanical properties and heat resistance. It is made from phenol and formaldehyde, with the addition of special toughening and modification agents, and is produced through advanced polymerization technology. It is a light brownish-yellow transparent solid with no obvious odor. It has excellent toughness and becomes structurally stable after curing, and is suitable for processing needs such as rubber high-strength reinforcement, high-end molds, and high-temperature composite materials.
Product parameters
| Appearance | Light brownish-yellow transparent solid |
| Softening point | 105 - 115℃ |
| Hydroxymethyl content | 12 - 16% |
| Free phenol content | ≤ 2.0% |

Product advantages
The core advantage is its excellent toughness. After curing, its impact resistance far exceeds that of conventional phenolic resins, and it is not prone to cracking; it has outstanding high-temperature performance, can be used for a long time at temperatures below 180℃, and is not prone to deformation or aging in high-temperature environments; it has strong adhesion, which can significantly enhance the strength and durability of rubber and composite materials; it has wide processing adaptability, with adjustable curing speed, and is suitable for various processes such as compression molding, coating, and pouring; it has low impurity content, mild odor, and takes into account both environmental friendliness and processing stability, making it suitable for use in high-end scenarios.

FAQ
Q: What is the main difference between 2201 and 1101 phenolic resins?
A: 2201 has lower free phenol content, a milder odor, higher bonding strength and softening point, and is more suitable for environmentally friendly and high-precision processing scenarios.
Q: Which products are they mainly used for?
A: High-end rubber reinforcement, environmentally friendly adhesives, high-precision molds, electronic component packaging, etc.
Q: What should be noted when using them?
A: Avoid mixing with strong oxidants. Control the curing temperature between 130-160℃. Store in a sealed, cool and dry place, away from high temperatures.
