β-crystalline Nucleating Agent for Polyolefins TMB-5
TMB-5 is an economical and efficient β-crystalline nucleating agent for polypropylene which can
induce β-crystallization to obtain β-crystalline polypropylene having high β-crystalline content to give
the products good impact resistance ,heat distortion resistance and high porosity. TMB-5 is especially
suitable for use in PP-R pipes, automobiles, household appliances and other modified products which
demand high impact resistance and heat distortion resistance, and also use in the production of high
porosity printable films such as PP man-made paper.

Applications & Features
TMB-5 is an economical and efficient nucleating agent for polypropylene, and it has the advantages of
improving the rate of crystallization, crystallinity and β-crystalline conversion,thereby gives the products
excellent impact resistance ,heat distortion resistance and high porosity. The testing data show that adding
0.3% TMB-5 to homopolymer and random copolymer polypropylene, the β-crystalline conversion is as
high as 90%, impact strength and heat distortion temperature are dramatically raised, and the former is
increased by 4-5 times, the latter is as high as about 127℃. It features a combination of enhancing clarity,
stiffness, surface gloss, thermal distortion temperature and other physical and mechanical properties.
Compared to other β-crystalline nucleating agents, TMB-5 has the advantages of non-coloring, improving
the deformability of products and excellent β-crystalline stability. TMB-5 can be blended with PP powder
directly, and also carry through secondary processing after being incorporated into masterbatch. The
recommended level is 0.1-0.3% of PP base.
Sanitation & Safety
TMB-5 is odorless and non-toxic. Handle with due care and avoid dust formation and keep away from
ignition sources.
Storage & Package
TMB-5 should be kept in a dry and well-ventilated place. It is packed in fiber drum or paper box with
a lining of plastic sack.
