ALITA L-5016 Low Profile (LP) Additive - Zero Shrinkage Rate & High Surface Quality

Principal Properties & Application:

ALITA L-5016 is a Low Profile (LP) additive specifically designed for Class-A surface SMC/BMC applications. Its exceptionally low viscosity and excellent shrinkage control enable the production of final products with precise shrinkage rates, including zero or even negative values. This makes it an ideal solution for products requiring high surface quality and accurate dimensional stability. Additionally, ALITA L-5016 exhibits outstanding heat resistance, water resistance, and weather resistance, meeting the demanding requirements of specialized products.

Usage instructions:

ALITA L-5016 is typically used in conjunction with ALITA 1506 for the production of low shrinkage molded plastics. Generally, the recommended ratio of ALITA L-5016 to ALITA 1506 is 50:50, but it can be adjusted as per specific requirements.
The molding conditions are set at a temperature of 140~160°C and pressure of 50~100kg/cm². Depending on the desired dimensions of the final product, it is possible to add 300ppm~600ppm of p-Benzoquinone to the formulation (calculated based on the total amount of resin and low profile (LP) additive).

Handling and Storage:

This resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn.
Drums - It is highly recommended that all material is stored at stable temperatures below 25°C (77°F). Avoid exposure to heat sources such as direct sunlight or steam pipes. To avoid contamination of product with water, do not store outdoors. Keep sealed to prevent moisture pick-up and monomer loss. Rotate stock.
