Process Operation Guide

Palapreg® P 171-909 is usually used in combination with Palapreg® H 892-02 for the production of low shrinkage products. The ratio of Palapreg® P 171-909 to Palapreg® H 892-02 is normally 6040, but can be adjusted according to actual conditions. Depending on the dimensional requirements of the final product, 300ppm to 600ppm p-benzoquinone can be added to the formulation (based on the total amount of resin and low-shrinkage additives).

We offer our products for sale in mainland China (in compliance withRegulations on the Administration of Internet Sales of Hazardous Chemicals ) and some of the products of the global export services, providing dangerous goods packaging containers, "outbound dangerous goods transportation packaging use identification results list", "outbound cargo inspection and quarantine" and other export procedures.
We have rich experience in exporting hazardous chemicals, covering Class 5.2 (including products for cold chain transportation), Class 3 and Class 9 dangerous goods. Our services have been extended to more than 40 countries worldwide, including the Middle East, Central Asia and Eastern Europe.
