2. Description
Silane cross-linkable EPDM rubber compound, based on EPDM and other copolymer, is produced and pelletized by special technology, adding some flame retardant, initiating agent, cross-linking agent, and some other suitable additives. This compound contains two parts A and B, which should be mixed according to suitable proportion when used. This compound has well performance of processing easily, physical properties, and cost advantage with low density.
3. Processing
The following temperature(℃) profile of extruder is recommended:
Type | Proportion of A and B | Processing Equipment | Compression ratio | L/D | Processing temp. | Cross-linkable conditions | |||||
Z 1 | Z2 | Z3 | Z4 | Head | Die | ||||||
GDWE1125 | 90:10 | It is better to use professional extruder for halogen free compound. If you use PVC extruder, the speed should be lower, reinforce cooling | 1.2~1.5:1 | 25:1~ 18:1 | 100 | 140 | 160 | 160 | 165 | 170 | Hot water or steam, based on the terms of more than 85℃, 4h/mm thickness cross-linking speed |
GYJE-20 GYJE-10 | 97:3 | Conventional PVC extruder | 2.5:1~3.5:1 | 25:1 | 110~170℃ | 180-190℃ | |||||
method of application:
1. When you use this product, please mix A and B before put into the hopper. If you need color, the cable factory can use the polyvinylene masterbatch. The material should be used up in 8 hours after being opened and the rest can be resealed and usable within 24 hours.
2. The extruder should be cleaned after stopping with PVC material, (It is preferable if you can take apart the screws to clean.)
3. The silane cross-linkable LSZH compound should not be stayed in the extruder for a long time .If it stayed for long time, it will pre-crosslink after open the machine, which will make lumps in the surface of cable. It need to be discharged all the pre cross-linker, and then produce the cable properly.
4. To ensure the safety and fully of the cross-linking, when immersed the compound into the hot water or steam, please calculate the cross-linking time based on the terms of more than 85℃, 8h/mm thickness cross-linking speed.
5. At room temperature, the degree of cross-linking can also meet requirements after 4-10 days. The specific time can be different according to the temperature and humidity.
Note:
1. Transportation: avoid direct sunlight and weathering and machine damage
2. Convey: discharge softly, put off softly, avoid from the bursting by the stressed with the aluminum-plastic Bag.
3. Storage: it can not be landing stack. It should be put on the pallet in the clean dry storage.
4. Keep dry: When the material used, it must not be contained the outer water. Otherwise, it will seriously pre-crosslink.
5. Quality guarantee period: 6 months after manufacturing.
4. Storage and transport
Packaging:Vacuum Aluminum foil and PE membrane inside bag, and kraft outside bag.
Storage and transport: Avoiding in direct sunlight and weathering. The storage place should be clean, cool, dry, and ventilated.
5. Properties
Note: The below data is got after the compound boiled in 80 degree C water 4 hours. Natural crosslink can also be finished at proper temperature and in proper time.

- Q: I'd like to know what PP plastic material is PP plastic raw materials cleaning can not use ultrasonic cleaning machine to wash it?
- PP plastic raw materials have many kinds, different plastics, different surface dirt, cleaning method is not the same. In the manufacture of PP plastic raw material, the plastic surface will come with the dirt after processing. The very good market survey, some production factory cleaning PP plastic raw materials, generally with caustic soda, washing powder, detergent to wash these plastic, the effect is not ideal.
- Q: Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?
- Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.
- Q: How are plastic products made? What is the raw material of plastics?
- Plastic products are divided into: injection molding, blow molding, spray molding, blister, and die casting. Plastic material is oil. It must be done at a high temperature. The mold you call is usually steel.
- Q: What is the material of plastic dip?
- DIP processing, in general domestic PE dip powder or PVC dip plastic liquid. Specific depends on product characteristics and characteristics. Under normal circumstances, outdoor products, such as large pieces of metal products, PE dip plastic powder used for dipping plastic processing. PVC dipping liquid is more used for anti-skid products.
- Q: How many kinds of raw materials are there for blowing plastic bottles?
- Plastic bottles are made of polyethylene or polypropylene and added a variety of organic solvents. Plastic bottles are widely used in polyester (PET), polyethylene (PE), polypropylene (PP) as raw material, add the corresponding organic solvent after high-temperature heating, the plastic mold by blow molding, extrusion blow or injection molding of plastic containers.
- Q: How do you increase the transparency and hardness of PP plastic suction pipes? What raw materials do you need to add?
- Choose the right material. If you don't think the transparency is enough, you can add a nucleating agent to modify it. PP's common transparent nucleating agent has the ability to increase transparency and improve the surface hardness of the product. Yuyao Zhenyi plastic
- Q: How to identify the proportion of nozzle material in plastic?
- It can be analyzed according to the melting point value (MFI/MI) of plastic material. Generally not to exceed the raw material index 30% judgment. Example: GE C1200 raw material MI value is 19., the judgment basis is: 19+19*30%=24.7, if the test result is more than 24.7 numerical value many, basically can judge the plastic performance not to be able to satisfy the request.
- Q: PVC what chemicals do you need for plastic surface treatment?
- Different processing methods are often required for different materials.
- Q: What are the materials for making plastic basins? Are they raw materials?
- Generally PP material, transparent is raw material, opaque is not necessarily
- Q: What is the difference between plastic particles and raw materials?
- Special plastics: thermosetting plastics, functional polymers, plastics, such as artificial kidney. Heart. Blood vessel。 Aerospace industry, etc.
