1) Excellent price performance ratio
2) Various color, smooth surface
3) 100% PU raw material
4)ISO9001

1.:Proportioning

   HL1336 : MOCA =100 : 10.65

2.:Craft

   (1).As the material is solid under the normal temperature,so it should be placed in 

        a 90 celsiuss oven to be heated before using to make it melt.

   (2).Taking a proper amount of the material in a container,make a degassing when 

         it is heated  to 90 celsius,until it without larger bubbles when visual.

   (3).Heat the MOCA until melting,mix up the two when the temperature of the 

        material is about 80 celsius,and then stir fast. 

   (4).Pouring the material to a 100 celsiuss mould,die after gel,open the mould 

        after about an hour.

   (5).Put the products to a 100 celsiuss oven ,make a vulcanization,it can have a 

        stable performance after 12-16 hours.

3.:Announcements:

   (1).The material should be timely sealed when it be taken out to prevent a moisture 

         absorrtion.

   (2).The material should be keep in a cool and ventilate place.
