Rubber adhesion promoter/BH-ZR-68

Compatible with our BH-HJ16 hot melt adhesive film, used for one-time molding of small foam molded midsoles and rubber outsoles.

Addition amount: 2-3% of the total adhesive mass; It has already entered the mass production process at Yuyuan and has stable performance.

Product Features:

Add to the rubber outsole formula to enhance the adhesion between the rubber outsole and the hot melt adhesive film; Add to the EVA foam midsole formula to enhance the adhesion between the EVA midsole and the hot melt adhesive film.

Reduce the occurrence of poor bonding such as empty packaging and inability to cut during the one-time molding process of the midsole and outsole; The addition of EVA foam midsole formula has a certain enhancing effect on the tear strength and peel strength of the foam midsole; After being added to the rubber outsole formula, it has a certain enhancing effect on the anti-skid and wear-resistant properties of the rubber outsole, participates in rubber vulcanization, and has no problem of frosting or whitening.

Product Advantages:

Adopting new technology reduces processes such as washing, roughening, applying glue, and drying in an oven; Reduced the discharge of waste gas and wastewater such as glue solution and water washing agent, and lowered VOC emissions. Improved the working environment for employees; Reduce costs (according to estimates, taking sports shoes as an example, the overall cost per pair of shoes is reduced by 0.2~0.7 US dollars).

Application Areas:

Compatible with various proportions of LDPE, EVA, POE, NR, BR, SBR, and almost all other ethylene or ethyl ester copolymers.

As thermoplastic plastics (PPS, PBT, PET) and PC/PBT, PC/PET, and PC/ABS alloys. And compatibility agents for polyester/polyolefin blends and certain formula tapes.
