FICO BESI test results Linqsheet carcinogen-free cleaning and conditioning rubbers

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.

1 Sum­ma­ry
This report con­tains the results made with the Caplinq LINQ sheet mate­ri­als, RCS400 Mold Clean­er and WS300 Mold Wax.
Goal is to test if these car­cino­gen free mate­ri­als are suit­able for clean­ing and con­di­tion­ing Fico/Besi Molds.

2 Set­up
Test­ing was done on MMS‑I “Moldtest2” at Besi Duiv­en the Nether­lands in week 25–2017. Mold used: 104337

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.
