Weight reduction and raw materials savings are only the first of many key advantages of foaming with HYDROCEROL chemical foaming agents (CFAs). Others include thermal and acoustic insulation, increased stiffness-to-weight ratio, improved surface texture and elimination of warpage and sink marks, together with more efficient processing.
HYDROCEROL CFAs produce foam by decomposing at processing temperatures, liberating gases into the polymer melt. The decomposition of the CFA can be either of an endothermic or an exothermic character. In contrast, physical blowing agents are gases or low-boiling-point liquids that are injected directly into the melt to produce foam.
Available in various sizes of granules and as powders, HYDROCEROL foaming and nucleating agents can be used for foaming almost all commonly used thermoplastic resins and blends, such as PP, HDPE, LDPE, LLDPE, PS, ABS, PET, PETG, PC, PC?ABS, PA, TPE, TPU, TPR and PVC.
The carrier systems of the masterbatches and additive combinations are specifically developed for a wide variety of processes. |
