SoliPaper LOWPAC

SoliPaper LOWPAC

SoliPaper™ LOWPAC

SoliPaper LOWPAC is our industrial grade paper grade, based on low bio persistence fiber, developed for large volume gaskets cutting in domestic appliances and automotive. Utilizing the SoliWool ULS® as base fiber, SoliPaper LOWPAC  LOWPAC has a classification temperature of 1260°C and is recommended for use up till 1100°C continuously.

SoliPaper LOWPAC is a spin-off based on the premium SoliPaper ULS®, but with a lower density and a slightly tighter thickness specification which make SoliPaper LOWPAC a more economical version which technically still outperforms most standard high temperature papers as result of our Generation III, Ultra Low Shot technology.

One of the comments, when customers start working with our standard SoliPaper ULS-grade, was that it was much stronger compared to standard high temperature fiber paper  In some large volume gasket applications this high strength and density was not required which led to the development of the lower density, but more economical, SoliPaper LOWPAC.

Utilizing an optimized production process, we are able to create a product close dimension tolerances, exceptionally low dust, high handling strength, and improved thermal insulating performance.  SoliPaper LOWPAC is particulary suited to all applications requiring further processing (laminated composites, die-cutting, rolling, folding).

As SoliPaper LOWPAC (like the normal SoliPaper ULS) is manufactured based on our SoliWool ULS, it also has a classification temperature of 1260°C and is recommended for use till 1100°C continuously.

SoliPaper LOWPAC is using organic binders which burn out on the first firing, starting at approximately 250°C.

All products in the SoliWool ULS fiber product range, like the SoliPaper LOWPAC, meet the requirements specified under NOTE Q of European Regulation 1272/2008. SoliPaper LOWPAC products are therefore exonerated from labelling requirements in Europe.

Next to the SoliPaper in the low bio persistence grade (LBP) we also offer a standard range of RCF(-Zr) Papers from 1260 to 1430°C and special paper grades using PCW fibers up till 1600°C.
