Low Smoke Halogen-free Additives

Low Smoke Halogen-free Additives

One of the most hazardous risks that might appear in any area is fire. Whether a fire occurs in a home or business setting, the results can be disastrous and include property loss, equipment damage, and even human life loss. Because of this, it is essential to take fire safety seriously and take all reasonable precautions to avoid having fires. Utilizing low smoke and halogen-free additives in your materials is one way to accomplish this.

Little smoke In order to improve the flame retardant qualities of materials like cables, wires, and plastic items, halogen-free additives can be applied. By lowering smoke and toxic gas emissions in the case of a fire, these additives increase the fire safety of materials. The additives function by lowering the pace at which materials burn and inhibiting the spread of fire.

Silicone, the scientific name is generally called siloxane, polysiloxane. The silicone powder used in the market is generally produced with higher molecular weight organic silicone plus silicon dioxide, which is to disperse siloxane into silicon dioxide. , low molecular weight silicone is generally liquid, we commonly known as silicone oil. But if the molecular weight is large enough, it can be made into a sheet-like solid.

The so-called silicone masterbatch, that is, diluted silicone (usually siloxane + silicon dioxide) with 50%-30% carrier and other additives. The carrier is generally polyolefin, which can be directly added as an inorganic Filler sizing used. The general modification industry seldom uses silicone oil (low molecular weight siloxane) directly because of its dispersibility defect. If you use silicone oil directly, you need to ensure sufficient dispersion to achieve the desired effect. Currently, it is commonly used in elastomers for modification (such as SBS, SEBS). First, it can change its wear resistance, and in addition, it can adjust its hardness. This process In the industry, it is usually called oil-extending. The products produced by this method have relatively large limitations in use and are easy to separate out, which is commonly referred to as oil-out.

After produced wire and cable when the extruder chamber will have residual glue, if the glue inside is not cleaned up, the subsequent production of wire and cable is prone to roughness, the presence of lumps and the problem of cracking of the glue seal. We have wire and cable additives.

Product characteristics
(1)Reduce screw torque, extend the service life of processing equipment, reduce processing energy consumption and improve production efficiency.
(2)Improve the processing fluidity of cable material, speed up the extrusion speed, and improve the mechanical strength of the cable.
(3) Reduce the heat release during processing, and is a synergist for the production of low smoke and halogen-free cables.
(4) Improve the surface gloss, color brightness and wear resistance of the product.
(5) Improve the temperature and cold resistance.

Many different industries can use low smoke, halogen-free additives, including: 1. Electrical: Due to the heat produced by electricity, electrical wiring and cables are particularly prone to flames. But these materials can be made a lot safer by adding low smoke, halogen-free additives. 2. Building and construction: Buildings are very flammable, and the issue is exacerbated by the use of chemicals and plastics during construction. Low smoke, halogen-free additives, however, can stop fires from starting and lessen the chance of harm and damage.

3.Transportation: To safeguard passengers and crew, high levels of fire safety are required in vehicles like buses, trains, and aircraft. The risk of fires can be greatly minimized by employing low smoke, halogen-free additives in the materials used in these vehicles.

Product use method
Select the adaptable model according to the requirements of the purpose of use, and choose the appropriate proportion of silicone plastic additives to add. Production
The production of cable material (granulation) in the operation process with lubricants or coupling agent added at the same time for mixing and Mixing. (According to the product requirements can reduce the amount of lubricant).

Suggested addition amount

When the addition amount is 0.5%-2.0%, it improves the processability, fluidity and demoulding of the products; when the addition amount is 1.0%-5.0%, it improves the surface performance of the products (smoothness, finish, scratch resistance, wear resistance, etc.). When added 2-5% for wear resistance, the abrasion can be reduced by 30-80%.
