Locomotive Cable Compound:
1. Applications and cable specifications:
Applied to the locomotive cables which voltage is less than 3KV and temperature is 125°C.And the cable is used in the no mineral oil and no fuel oil environment.
2. Description:
Irradiation cross-linkable, low smoke halogen free and flame retardant POE compound for locomotive cables, based on special high oil resistant POE resin, is produced and pelletized by special technology with adding special stabilizing agent, modifier, halogen free flame retardant, cross-linking agent, antioxidant and other special additives. It meets the locomotive cable requirements of high temperature resistant and oil resistant.
3. Processing:
Irradiated dosage:12-15 megarad
The compound can be processed with conventional extruders, and the normal PVC screw with a minimum 20:1 L/D. It is better if use low compression ratio screw.
The following temperature(°C) profile of extruder is recommended:
| Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
| temperature °C | 130 | 145 | 150 | 150 | 145 | 145 |
4. Storage and transport:
Packing: 25kg/bag, PE membrane inside bag and craft outside bag.
Avoiding in direct sunlight and weathering.
Storage place should be clean, cool, dry and ventilated.

- Q: What are the raw materials of foam plastics and how do they come out?
- More bisphenol A epoxy resin, epoxy value of 0.51 ~ 0.22mol/100g. When the viscosity is 25 degrees centigrade, it is 20Pa / S; the viscosity is 130 s at 1Pa.
- Q: What material is best for plastic gears?
- At present, the demand for plastic gear with high wear resistance and noiseless gear is very strong. POLYMSJ noiseless nylon composite occupies a leading position in this field. If it doesn't solve the problem, you can try it out.
- Q: Plastic raw materials packaging is generally divided into several categories?
- 1, cattle cardboard fiber bag; "such as: GPPS, HIPS CMO ABS, are using this package, he is in some plastic packaging,2, fiber bags, plastic bags, such as PP or PVC, PE and so on3, plastic bags, Exxon, Teijin etc.4, plastic bags contain tin and platinum paper, for sealing requirements or moisture absorption of the material packaging5, kraft paper bags, PBT, PET, PPS, PA and so on
- Q: What are plastic materials extracted from?
- Plastic is made of petroleum or natural gas as raw material, through refining, cracking into a variety of petrochemical raw materials (monomer), and then through polymerization (adding polymerization or condensation polymerization) derived from high polymer resin.
- Q: How to identify the proportion of nozzle material in plastic?
- This result has two conclusions: 1, with large ratio of feed back. 2, the molding process causes the plastic cracking phenomenon to be more serious. The following is a screenshot of the performance of the material. It is important to note that the same plastic has different data downstream of different test conditions, so it is necessary to refer to the test conditions on the physical chart.
- Q: Will plastic raw materials (such as PET, PP, etc.) be made of non-woven fabrics, will certainly contain BPA?
- Only PC (polycarbonate) is available.If the customer is not sure, you can take your product to the third party organization testing, prove that you can do without BPA, and ask your supplier to provide inspection reports and guarantee without BPA.
- Q: ABS plastic storage conditions
- If it is ABS raw materials, storage: rainproof, moisture-proof, anti lightPacking is best provided with a PE inner bag for moisture proofThere is no place to pay more attention.
- 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: How to test plastic raw materials?
- Thermal stability test of size and appearance quality. Place the product in a 8020C oven, 24H, and cool down to 2350C (2H). Measure the size of the same measuring point before and after the test, and calculate the percentage change rate. And observe the appearance quality changes, dimensional change rate of <0.2%, appearance is not allowed to have deformation, crack, expansion, surface gray, discoloration and other phenomena.
- Q: What are the criteria for the classification of plastic materials at injection molding and extrusion?
- Plastic material is injection molding or extrusion grade, there is no standard, but there is an applicable reference value, that is, the material "melt flow rate" value.
