Description

UNICELL-OH series is an outstanding non-staining, non-discoloring nitrogen-releasing foaming agent for the production of both cellular rubbers and plastics. Among the latter, PE, PVC, epoxy, TPR, and phenolic resins are currently expanded on a commercial scale using these foaming agents. It can also be used in the production of thermal insulation materials based on blends of synthetic rubbers and thermoplastics, e.g., NBR-PVC.

UNICELL-OH series produces ammonia-free gas upon thermal decomposition.

The decomposition temperature of UNICELL-OH series aligns with the conventional curing temperature range.

UNICELL-OH series therefore provides good foaming efficiency at conventional curing temperature without the need for activators.

Properties of UNICELL-OH series

Applications

UNICELL-OH series can be used for foaming PVC, EPDM, EVA, LDPE, CR, and other resins.

UNICELL-OH series is suitable for PVC plastisol and calendaring, as well as extrusion, injection molding, and other thermoplastic processing.

Decomposition of the UNICELL-OH Series

The decomposition of UNICELL-OH series, nitrogen gas is produced as follows:

The solid residue is a non-polar, aromatic, sulfur-containing polymer, which accounts for approximately 84% of the original weight of UNICELL-OH.

Activation

The decomposition temperature of UNICELL-OH series can be lowered by various types of activators.

The effect of activation on the decomposition of UNICELL-OH series depends on the type of activator and the processing conditions.
