PHENOL-FORMALDEHYDE RESIN - Physico-chemical Properties
| Molecular Formula | (C6H6O·CH2O)x |
| Molar Mass | 124.0524 |
| Physical and Chemical Properties | Usually refers to the phenol or its homologs (such as cresol, xylenol) and formaldehyde and the role of liquid or solid products. Depending on the type of raw materials used, the ratio of phenol to aldehyde, and the type of catalyst, two different types of thermoplastic and thermosetting resins can be obtained. The thermoplastic phenolic resin (novolak resin) only melts when heated and cannot be changed to an insoluble and infusible state. But after the addition of curing agent (such as hexamethylenetetramine) can be converted into thermosetting, with trifunctional or difunctional phenols as raw materials, in the amount of phenol (molar) more than the amount of aldehyde (molar) and acidic catalyst conditions. The thermosetting phenolic resin changes to an insoluble and infusible state after being heated. Phenolic Resin acid-resistant, alkali-resistant, heat-resistant. |
| Use | It is used as a tackifying resin for butyl chloride adhesive and a vulcanizing agent for butyl rubber. Store in a cool, ventilated warehouse, away from fire, heat source. |

PHENOL-FORMALDEHYDE RESIN - Preparation Method
phenol and formaldehyde in the presence of alkaline catalyst, such as alkali metal, alkaline earth metal oxide or hydroxide, appropriate control of the end point of the reaction, condensation. Due to the effect of hydroxide on the electrical properties, the latter part of the reaction needs to be neutralized with acid and desalted. The resin used as the electrical insulating material generally uses organic amines, such as triethylamine, triethylenetetramine, hexamethylenetetramine and other curing agents.

PHENOL-FORMALDEHYDE RESIN - Safety
Open Data Verified Data
resin production raw materials, the skin and mucous membranes of the human body have different degrees of stimulation, can cause skin allergic reactions and inflammation; At the same time also pay attention to the harm of resin dust on the human body, long-term inhalation of high concentrations of resin dust, can cause lung lesions. Most resins have
There is a common hazard characteristics: open fire, high temperature flammable, and oxidant exposure to cause combustion risk. Therefore, the operator should improve the operating environment, the operation area and the non-operation area are consciously divided, as far as possible automation, sealing, installation of ventilation facilities and so on.

PHENOL-FORMALDEHYDE RESIN - Introduction
Nature:
1. Phenolic resin has excellent heat resistance, chemical resistance, mechanical properties, and insulation properties.
2. Has good adhesion and can firmly bond multiple materials.
3. Has excellent wear resistance and corrosion resistance.
Usage:
1. Used as an adhesive: widely used for bonding materials such as wood, paper, and fiberglass, preparing plywood, synthetic wood, etc.
2. Used as a coating: It can be used as a wear-resistant coating, anti-corrosion coating, etc.
3. Used as plastic: can be used to prepare high-temperature plastics, insulation materials, etc.
4. Used for preparing refractory materials, friction materials, insulation materials, etc.
Method:
Phenolic resins are generally obtained by condensation of phenol and formaldehyde under alkaline conditions. Catalysts such as iron oxide and copper oxide are usually added during the reaction process.
Security information:
1. Phenolic resin is irritating to the skin and eyes, and protective equipment is required during operation.
2. Long term exposure or inhalation of phenolic resin vapors may cause respiratory irritation and skin allergies.
3. Phenolic resins should be avoided from being exposed to high temperatures or open flames to prevent their decomposition and the generation of harmful gases.
