摘要:
The present invention provides a member in contact with a rubber material, the member being characterized in that the member has a surface in contact with the rubber material, and that the contact angle of the surface thereof in contact with the rubber material is 40° or more when a liquid rubber to be tested is placed on the surface.
摘要:
In order to manufacture flexible plastic bands of a thermoplastic synthetic resin containing 40% or more by volume hard materials and/or soldering powder, two grooved and heated shearing rollers arranged parallel to one another and running in opposite directions are used onto which components are applied. The front shearing roller must have a temperature of 25.degree. to 90.degree. C. on the application side and of 30.degree. to 80.degree. C. on the removal side, the rear shearing roller must have a temperature of 30.degree. to 130.degree. C. on the application side and on the removal side of 35.degree. to 100.degree. C., and the temperature of the rear shearing roller must be at least 5.degree. C. above the temperature of the front shearing roller. In addition, the front shearing roller must exhibit a speed of 5 to 25 rpms and the rear roller a speed which is 5 to 70% lower.
