HD-IS-8710 Self-integral skin PU foam systems

Beijing Maohua PU Building Materials Co., Ltd.

HD-IS-8710 is four-component PU foam systems specially designed for self-integral skin products. B-component is modified polyisocyanate(MDI), while A-component is made up of polyether polyalcohol,blowing agent,catalyst and stabiliser,etc. C is blowing agent; D is colour paste. All of these are separate packaging. The systems has three kinds of brands.

*  HD-IS-8710H is applied to products with higher hardness requirement, such as the steering wheel of trucks and vehicles' bumpers.

*  HD-IS-8710S is applied to products with medium hardness, such as the armrests of chairs and steering wheels of cars.

*  HD-IS-8710L is applied to PU products with low density and hardness, such as cushions, backrests, supports and toys of physical, gymnastic and medical equipemnt.
