Recently, CAPLINQ introduced two new products: Linqsheet RCS400 carcinogen-free rubber cleaning sheets and Linqsheet WS300 carcinogen-free wax conditioning rubber. These two products have been introduced as an alternative to the current rubber cleaning and conditioning materials that are common in the industry.
As important as it is to be carcinogen-free, it is of course equally important to be very good cleaning and conditioning compounds on epoxy molds. The best way to test the performance of these materials is to ask FICO/BESI the industry leader of epoxy molding machines to test these products on their molding equipment.
Below is the 64-page report of the rubber cleaning and conditoning waxes. In summary, it shows that both the Linqsheet RCS400 and WS300 are comparable to the current industry standard materials in terms of both cleaning and conditioning of the epoxy molds. However, both materials are a slightly higher in viscosity. This is not a problem for most epoxy molds with standard cavity sizes, but molds that have very small cavities may need a little more process work to perfectly optimized.

Below is are the notes taken from the test report itself.

Summary of CAPLINQ Chemlinq WS300 and RCS400 Rubber Cleaning and Conditioning test results
Testing shows that the new RCS400 is more viscous than the current material.
This results in incomplete filling of package cavities.
The WS300 conditioner shears when being removed from the mold, resulting in partially filled cavities.
