| HYDROCEROL Concentrates are specified worldwide to reduce weight, improve performance, and optimize costs in products ranging from business machine housings, food and medical packaging to material handling systems, automotive parts and window profiles. |

The HYDROCEROL ITP Series is designed for use in thin-wall parts requiring the elimination or reduction of sink marks and warpage. Typical examples are injection molded automotive and electronic parts, as well as appliance housings. ITP Series foaming agents will produce a micro-cellular foam with no adverse influence on surface appearance. The use of these products may lead to density reductions of 5 to 10% and lowers resin consumption.

When used in the structural foam molding process, chemical foaming agents generate a cellular foam structure in the part interior. This technology delivers many advantages, including the following:
- Reduced part weights
- Reduced cycle times
- reduced warping and sink marks
- Improved melt flow
- Improved dimensional stability
- Enhanced specific mechanical properties
|
In foam injection molding, the foaming agent masterbatch (or powder) is either mixed or fed together with the polymer. The reaction of the CFA and the compression of the gaseous components are comparable to those in the extrusion process.
