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:

Q:What material do you need for plastic film? Do you use this material?
Plastic bags, quality, food grade requirements, the use of brand new HDPE (low pressure polyethylene).
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!
High density polyethylene (LDPE) transparency, the equivalent number can reach about 90%, but the temperature should be controlled well, there is no general problem, that is, the cost is higher than other products
Q:What plastic material is used for plastic hose?
ABS pipe: good corrosion resistance, light weight, heat resistance is higher than PE, PVC, but the price is more expensive. Bonding, flange thread connection, sanitary ware sewer pipe, gas pipe, sewage pipe, underground cable pipe, high anti-corrosion industrial pipe, etc.
Q:I do PA, PC, PP and other plastic raw materials can be used in the eye frame and lens it
In general, the lenses of PC need to be covered with scratch resistant protective films, which will be sufficient for better aging, and most lenses for children.
Q:That kind of plastic bottle blows well
PETA hard, tough, high strength, bright surface with transparent and multi colored sheets. The disadvantage is PET high frequency synthesis is difficult, the price is a bit more expensive than PVC, this material is often high-grade products and environmental requirements of the user to replace the PVC PET material generally used to make packaging for food, beverage, pharmaceutical plastic bottles.
Q:What is the difference between ABS plastic raw materials and recycled materials? Or how to distinguish between raw materials and recycled materials?
1. recycled material is not natural (ABS is yellow).2. non black pellets with black spots are recycled.3. the impurity in the aggregate is the recycled material.4. of the voids in the pellets are recycled.5. do MFI test, the result is more than 10% of indicators are recycled material.6., feed heating, smell, smoke, melting temperature is low, fast flow is recycled material.
Q:PP plastic stool surface with those raw materials, what is the ratio?
In general plastics, PP has the best heat resistance, and its thermal deformation temperature is 80-100 DEG C and can be boiled in boiling water.
Q:Low pressure plastic raw materials in the process of blowing the two sides of the fold, how to deal with?
The blowing ratio is one of the control points of blown film production and! Refers to the ratio between the bubble diameter and the diameter of not blowing blowing after.
Q:Characteristics and uses of CA plastics
Commercially available products can be divided into general cellulose acetate (acetyl - 37% - 40%). Plasticizers are often added as injection molded parts, such as toothbrushes, brushes, etc.. Cellulose acetate with a high acetyl content (40% to 42% acetyl), white, granular, powdery or cotton solid. The light stability, not easy to burn, in dilute acid, gasoline, mineral oil and vegetable oil in stability, swelling in chloroform, insoluble in acetone, methyl acetate, can dilute alkali erosion, has advantages of toughness, transparency, good gloss, good melt fluidity, easy molding. Dichloromethane homogeneous method using refined cotton linter and acetic acid with acetyl sulfate as catalyst, esterification, hydrolysis in the presence of dichloromethane solvent, can be combined with cellulose acetate acetic acid content in 60% + 0.5% range. The traditional method is to use dry cotton, acetic acid in the presence of catalyst activation, sulfuric acid, acetic acid and acetic anhydride with mixture of acetylation, then adding dilute acetic acid hydrolysis to belong to the degree of substitution, and catalyst, precipitation, acid washing, rice drying. After partial hydrolysis, cellulose acetate is called two, and the degree of esterification is 220~270. Without hydrolysis, that is, the degree of esterification, the gamma value of 300, said three cellulose acetate. Two cellulose acetate plastic handle, can do all kinds of tools of computer and typewriter alphanumeric keys, phone chassis, car steering wheel, textile equipment parts, radio switch and insulation, pen, spectacle frame and lens, toys, daily necessities, but also do desalination membranes. Three cellulose acetate, high melting point, can only match into solution processing, used as a movie film, X film, light film, electromagnetic diaphragm insulating tape, transparent container, the silver zinc battery.
Q:What is the difference between PPA plastic raw material and PP?
PPA is a high temperature nylon, generally used in the automotive industry and the electrical and electronic industry, it has the characteristics of high temperature resistant nylon, but also much higher than nylon, that is to say in the high temperature working environment inside it will be more excellent performance than ordinary nylon, longer service life. At present, the high temperature nylon base material on the market is basically nylon 46, nylon, 6T, 9T and so on.
