Professional R&D and excellent quality plasticizer chemicals

The company already has two grades of the alkylsulphonate ester-based plasticizer — the standard grade and a ‘low volatility’ grade. With the new grade, Bayer says it expects to improve haze performance by reducing the Hazen colour number from 300 to around 100, and to reduce the phenol content from 14 ppm to around 10 ppm.

Bayer is working on improving its Mesamoll plasticizer range with the development of a new low-haze grade.

Bayer Chemicals, has added a new polymeric plasticizer to its polymer additive range. The innovative trial product Ultramoll VP SP 51022 was developed for the rubber-processing industry, for use in applications such as the manufacture of NBR-based printing rollers. The plasticizer helps to produce highly flexible rubber articles - with no

The obtained bio-based plasticizer with flexible long alkane chains and polar benzene ring groups showed improved volatility resistance and solvent extraction resistance. The introduction of BPDC improved the thermal stability of PVC films due to the thermal stability of the ester groups and benzene groups of BPDC.
