Due to the variety of commodity specifications, all commodity specifications and prices are in good agreement with the owner. Buyers in front of the baby must first contact the owner, talk about good product specifications and prices. If photographed, do not contact the owner, the shop will not be shipped,
Friends and relatives, please note: all customers in this shop to buy products are considered to have read this "notice""!!!
1. on Freight: this shop does not bear all the material freight. As per customer is located away from the place of delivery is not the same, the purchase amount is not the same, so the shop not in freight superscript is how much will be labeled as "the seller" please see clearly again before taking orders, please contact the owner! Freight according to the actual collection, logistics is generally to pay, the shop does not charge any freight.
2. on price: because this shop is too many products, specifications, every customer demand is not the same, please buyers to take before you contact the seller. The materials required specifications. (where the use or in accordance with the requirements of buyers or cutting processing materials shall not be returned)!
3. please confirm each buyer material packaging is complete in the sign before, because we each batch of goods are inspected before packing, if after receipt of material damage, any problems of this shop is not responsible.
 
Properties of 3240 epoxy plate:
 
 
3240 epoxy laminate plate surface smooth, no bubbles, no pits and wrinkles, but allow does not affect other defects, such as: using scratch, indentation, stain and a few spots. The edge should be cut neatly, and the end face shall not be divided into layers and cracks.
Implementation criteria: GB/T1303.1-1998.
Temperature tolerance grade: B
Color: natural (yellow), green, etc.
Characteristics: after curing epoxy resin system has excellent mechanical properties, high temperature strength Jie machine, good electrical properties under high humidity.
Electrical property: the cured epoxy resin system is a kind of excellent insulating material with high dielectric property, surface leakage resistance and arc resistance
Usage: suitable for mechanical, electrical, electronic, electrical and other fields. Also used in the processing of insulation parts, processing into all kinds of insulation parts and equipment insulation structure parts.
Thickness: under normal circumstances is 0.3 ~ 50mm, can also be required to produce 50~150mm thick plate.
The epoxy resin and the curing agent reacts by direct addition reaction or resin molecules of the epoxy group ring opening polymerization, no water or other volatile by-products release. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.
 
 
Brief introduction of materials:
 
Epoxy resin is a polymer compound, a molecule containing two or more than two epoxy groups, in addition to individual, their relative molecular mass is not high. The molecular structure of epoxy resin in the molecular chain with lively epoxy group as its characteristic, the epoxy groups can be located in the end of the chain, or intermediate molecules into ring like structures. Because the molecular structure of epoxy containing active, so that they can be cured with various types of agent crosslinking reaction and the formation of insoluble and infusible polymers with three direction mesh structure.
 
Application characteristics:
 
1, a variety of forms: all kinds of resin, curing agent, modifier system almost can adapt to all kinds of application form of the request, which can range from extremely low viscosity to high melting point of solid.
 
2, curing convenience: choose a variety of curing agents, epoxy resin system can almost cure at 0~180 degrees of temperature range.
 
3. Strong adhesion: the existence of polar hydroxyl group and ether bond inherent in the molecular chain of epoxy resin, so that it has a very high adhesion to various substances. When epoxy resin is cured, the shrinkage is low and the internal stress is small, which also helps to improve the adhesion strength.
 
 
4, low shrinkage: epoxy resin and the curing agent reacts by direct addition reaction or resin molecules of the epoxy group ring opening polymerization, no water or other volatile by-products release. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.
 
5. Mechanical properties: the cured epoxy resin system has excellent mechanical properties.
 
6. Electrical properties: the cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance.
 
7. Chemical stability: usually, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy system, the chemical stability depends on the selected resins and curing agents. Proper selection of epoxy resin and curing agent can make it have special chemical stability.
 
8. Dimensional stability: the synthesis of many properties above makes the epoxy resin system have outstanding dimensional stability and durability.
 
 
9, mildew resistance: cured epoxy resin system resistant to most mold, can be used in harsh tropical conditions.
