Nucleating Agent BT-20
1.Introduction
Nucleating Agent BT-20 is an aluminium aromatic carboxylate, which is substitute for AL-PTBBA of Shell
Japan Ltd. It can supply nucleus and accelerates the rate of crystallization which makes the structure of
crystal grain finer. It odorless, tasteless and no toxic.
Accordingly, many characteristics of the product can be improved, including the firm of the material, yield
strength in tention,strength of impact, flexural modulus, the temperature of heating distortion, stability.
