In accordance with the features of thermal shrinking industry ,the company releases the special flame retardant of thermal shrinking .The product is compliance with EU ROHS environmental protection directives and enables to fulfill the purpose of high-filling and halogen-free flame retarding as well as meets various requirements of domestic thermal shrinking industry for high performance and low costs.

At present,lots of thermal shrinking manufacturers use the products of our company.It is proud of good using effects and fully reaches the requirements of thermal shrinking industry for flame retarding and mechanic performance.

Product Advantages

1.High processing temperature and excellent plasticization effects as well as high surface gloss of products.

2.The size is uniform,Wide Chemical Compatibility, Mechanics performance effect is small.

3.High content.high whiteness degree.small color effect.

4.With large filling quantity ,it can greatly reduce the costs of thermal shrinking products.

Magnesium hydroxide flame retardant masterbatch for heat shrinkable materials

This product has magnesium series fire retardant as the main raw material, in which surface modifier is added and which is subject to refined compound coupling treatment in continuous activation and modification equipment. Then a small amount of assistants, such as ethylene-vinylacetate copolymer (EVA), macromolecular compatilizer, etc., are added for manufacturing through sufficient mixing, plastifying, extrusion and pelletization.

In comparison with the traditional powdery magnesium hydroxide product, this fire-retarding parent material is easy to disperse, blend with no powdery dust, good plastification, low energy consumption, high output, being a green and eco-friendly product.

Product Advantages

1. As there is no such problem as flying powdery material during the use of the parent material, there is no influence on workers’ health and workshop environment in production.
2. This dedicated parent material is good in fire retarding. The fire retarding level can reach V-0 class.
3. In production application, this fire-retarding parent material has no phenomena of material affixation to wall, hanging, stoppage, bridging, etc. and the problems of inaccurate automatic metering, etc. can be effectively avoided.
4. In addition to excellent fire protection performance, the heat shrinkable material produced by using this parent material has also solved the problem of serious reduction in tensile strength and rupture elongation due to uneven filling agent dispersion.
5. In producing heat shrinkable materials with this parent material, the production process is very simple. The manufacturer only needs to add EVA resin, masterbatch and fire-retarding parent material. It is not necessary to further add any modifier, red phosphorus, lubricant, etc.
6. Producing heat shrinkable materials with this parent material can reduce the comprehensive cost of the whole production process. The labor cost and environmental cost in the production process will reduce substantially, and the amount of the fire-retarding filling filled can be heighted to reduce the raw material cost.
