Fire retardant polyether polyol- General Introduction(SGS authenticated)

    There're two ways for fire-retarding: Fire-retarding agent or fire-retardant polyol. Fire-retarding agent takes part in the reactor in form of addition agent. It takes up about 35% of the whole addition agent system. Usually it contains elements like halogen and phosphorous. When approached to fire, it'll generate a great deal of black smoke and poisonous gas, which disables it to be used in the fields that have high requirements, such as fire-retardant and environment protecting. Fire-retardant polyol makes it work by chemical reaction in which polyol is grafted with fire-retardant group and then brought into foam products, which makes polyurethane itself possess fire-retardant function. Our POP product belongs to the second way. By bringing non-halogen and non-phosphorous fire-retardant group into common polyether polyol, there's no need for any fire-retarding agent, and also reduce other raw materials' quantity. which saves production costs; when approached to fire, it generates nontoxic, low density, white smoke, which reaches the requirements of all kinds of International fire-retardant and environment protecting authentication.

    Fire-retarding agent possess following functions: Decompose and generate non-inflammable substance when close to burning temperature; React with foam burning-left substance to generate non-easily-flammable substance; Decompose and generate substance that terminates the oxidation of foam free radical.

    Normally, the capacity of fire retarding is achieved by adding fire-retardant agent that contains halogen or phosphorous, or adopting POP with fire-retardant structure. This can enhance fire-retarding property to postpone combustion, retard smoke and even self-extinguish the inflamming part.

    PU foam is a kind of combustible polymer as others, with very low density and large specific surface area. It's easy to combust. When it burns, it'll generate a lot of poisonous smog. Since the high rate of opening cell, the oxygen index without fire-retardant is only 17-18. Due to high ventilation, abundant oxygen is provided continuously, which makes it inflammable and never self-extinguish. Thus modify the bad fire-retarding capacity is very protruding. Many markets such as building material, furniture, cushion, mattress, etc., in which PU foam widely applies, require fire-retarding.

Why can our Polyether Polyol saves costs while improves the capacity of PU foam?

    This product, winning the National Innovation Patent (patent No.: ZL011341440), invented by Professor Zhulvmin, who's the leading figure in the field of PU and granted lifetime subsidy by the State Department. Zhejiang U-SUN Group Huzhou Innovative Polyurethane Technology Co., Ltd is entitled to manufacture and Zhejiang U-SUN Import&Export Co., Ltd is entitled to sell.

Technique and Rights:

Package:

5. We provide expertise technical services. With a special lab, research and development workshops and an expertise after service team, well develop new optimized compounding based on the original ones of our clients and definitely assure the safe, stable production. We can also supply A-part directly by your order. 

4. PU foam made of our POP has good opening-celled capacity, anti-scorching, improves and stabilizes the physical and mechanical property of PU foam.

3. With good technical application and compatibility with other PU raw materials, our product is suitable for molding, slabstock foam formation. And it can be used for producing common, high-resilient flexible foam with different density.

    When approached to flame, the foam surface will turn into black shell shape net and self-extinguish without melting drop. Because of the excellent functions as mentioned above, PU foam made by our POP can easily reach the requirements of every fire-retarding and environment-protecting authentication.

2. When close to flame, PU foam made of our POP emits less smoke than others, because ours doesn't need to add any fire-retardant agent. Also, the smoke is white, low-density and nontoxic; Zero VOC, oxygen index 28-36.

1. Tested by several professional PU foam manufacturers, it's verified that our POP can reduce the production cost of PU foam by 2-8%. Meanwhile, the properties of PU foam won't be changed but even will be improved. By graft modification, our POP can greatly reduce other raw materials, especially fire-retardant agent which are needed for PU foam production. That is how we save your cost.

Innovation and Advantage:

    We have two normal types now, SPPG-280 series and POP-290 series. SPPG-280 is for normal resilient flexible foam, and POP-290 is for high-resilient foam. We can customize new types for your special demand. Check details from introduction of SPPG-280 and POP-290.

    This is a high-tech product, which wins national innovation patent. It is a new type environmental-friendly non-halogen, non-phosphorus fire-retardant POP, which is used for flexible PU foam.

General Introduction:

eco-friendly, non-halogen, non-toxic, save production cost, designed for flexible PU foam without flame retardant additive.
