We carefully chose the cleanest and best base rubber for our mix.
Raw rubber is mixed with a number of other carefully measured high quality ingredients.
The uncured rubber is passed through a three roll calendar to achieve a controlled thickness and to apply the plastic liners.
The finished mill roll is sent to the die cutting department to be packaged and cut into strips, pre-cuts, rolls or squares.
