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: What are the materials for making plastic buckets? How many are there?
- There will not be a big gap, and some materials are good toughness, and some of the high strength, the original particles are basically not much difference. If it's recycled, that's hard to say.
- Q: What type of raw material is used in plastic bags? The brightness is good. It blows out as bright as a mirror! That kind of transparency!
- LDPE high pressure 2424H, Lanzhou petrochemical, LLDPE, 7042N, Lanzhou petrochemical. Transparency can reach 90%. The temperature should be controlled during blowing.
- Q: What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?
- Plasticizers can increase plasticity and softness of plastics, reduce brittleness, and make plastics easy to process and shape. Plasticizers are generally miscible with resins, nontoxic, odorless, and highly volatile organic compounds that are stable in light and heat. The most commonly used are phthalate two formic acid esters. For example, the production of PVC plastic, if you add more plasticizers, you can get soft PVC plastic, if not added or less plasticizer (dosage <10%), then hard PVC plastic.

Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flowers" laudatory title. It is the most important and most important material in plastic packaging and printing.
- Q: What are the raw materials needed for making plastic bags?
- Plastic bags, quality, food grade requirements, the use of brand new HDPE (low pressure polyethylene). Or LDPE (high pressure polyethylene). Or a mixture of the two.
- Q: What is the raw material for producing corn starch plastic film?
- At present, China's maize production in 1.31.5 million tons, only 1/10 of the corn crop is processed into starch, used in the textile industry, paper industry, food industry, medical industry and other fields, the total amount of nearly 10 million tons of starch (including corn starch close to 9 million tons; 420 thousand tons of cassava starch, potato starch, 240 thousand tons).
- Q: What are the properties of plastic material PS? What are the advantages and disadvantages?
- The parameters of PS plastic (polystyrene) English Name: Polystyrene weight: 1.05 g / cm3 molding shrinkage rate: temperature: 170-250 degrees 0.6-0.8% molding material properties of electrical insulation (especially high-frequency insulation) excellent, colorless and transparent, light transmittance after organic glass, color of water resistance, good chemical stability, strength, but brittle that is easy to produce stress cracking, no resistance to benzene. Gasoline and other organic solvents. Suitable for production of transparent insulation. Trim and chemical equipment. Optical instrument parts forming performance.
