New polyurethane prepolymer

Bayer Polymers introduced a polyurethane prepolymer under the trademark Baytec ME-120. This prepolymer combines the advantages of Baytec's completely solid prepolymer ME-090 with the pure prepolymer Baytec ME-230. With the use of hot-casting or low-cost disposable processes, ME-120 quasi-prepolymers can produce polyurethane elastomers with excellent physical properties. Can be applied to C-shoe wheels, industrial casters, valve sockets, rubber rollers and sheets.
Baytec ME-120 quasi-prepolymers are liquid at room temperature and can react with 1,4-butanediol at relatively low temperatures, and require little post-curing. As a quasi-prepolymer, Baytec ME-- 120 reacts with a mixture of 1,4-butanediol, polypropylene glycol and polytetramethylene glycol in a certain ratio. In the production of elastomers in the Shore hardness range of 50A to 60D, suitable catalysts should be selected. Baytec ME--120 quasi-prepolymers provide excellent formability and high reproducibility.
Baytec ME--120 quasi-prepolymer is a modified MDI--PTMG polyether prepolymer that can be used in hot-casting or primary processing to produce high-performance solid elastomers.


Eyelet Machine

This machine is used for punching,binding and riveting the eyelets on the papers in one operation with the eyelets feeding automatically in high efficiency.Once riveted, the eyelets will not easily broken off and are looking nice and smooth on the products without any scratches. 

The eyelet machines are widely used for paper bags, paper boxes, cartons, archive bags, document bags, secret documents, files, certificates, cards, hangtags,box seal and so on. 


Features,
1.The machine can automatically punch or continuously punch and rivet eyelets.
The punching and eyeletting can be finsished in one operation.
2.adjust hole distance freely according to the requirement.
3.The riveted shoes holes are are neat, beautiful and ametabolic with no scratches. 
4.Easy operation and reliable performance.
5.The efficiency is 8-15 times than manual operation.
