CAS 1314-13-2 High Active Nano ZnO Powder is high activity nano zinc oxide tailored for EPDM foaming rubber. It features small particle size and excellent dispersion. It works as vulcanization activator to accelerate crosslinking, stabilize foaming cells, uniform foam structure, improve elasticity and compression resistance of EPDM foaming materials while lowering usage amount.

Product Detail

CAS 1314-13-2 High Active Nano ZnO Powder for EPDM Rubber Foaming Materials

Product Overview

High Active Nano ZnO Powder (CAS 1314-13-2) is specially developed for EPDM foaming rubber systems. Produced via advanced nanometer synthesis and purification technology, the material features ultra-fine particle size, large specific surface area and outstanding dispersion in EPDM compounds. It acts as a high-efficiency vulcanization activator, coordinating the vulcanization crosslinking and foaming reaction synchronously. It helps form uniform and stable closed-cell structure, effectively improving elasticity, compression resilience and weather resistance of EPDM foamed products while enabling reduced addition dosage compared with conventional zinc oxide.

Core Features

High vulcanization activity: Accelerate crosslinking reaction of EPDM rubber, balance vulcanization rate and foaming speed.
Stable foaming performance: Promote homogeneous cell formation, avoid large pores or cell collapse, achieve consistent foam appearance.
Excellent dispersion property: Less agglomeration, evenly distributed inside EPDM matrix for stable batch quality.
Lower recommended dosage: Reduce filling quantity to cut raw material cost without sacrificing finished product performance.
Enhanced physical properties: Improve compression set, tensile strength and ageing resistance of EPDM foaming materials.
Good weather resistance matching: Fit outdoor EPDM foam products with long-term anti-ultraviolet performance.

It is also compatible with other synthetic rubber foaming formulas.

Usage Guide

Add nano ZnO during internal mixing of EPDM raw materials. Adjust dosage properly lower than ordinary zinc oxide. Control mixing temperature and mixing time to guarantee uniform dispersion. Optimize formulation to coordinate accelerator, foaming agent and nano ZnO for ideal cell structure. Carry out small batch foaming test before mass production. Keep packages sealed to prevent moisture absorption and activity decline.
