Clarifying additive approved for food contact applications
Februaw 1990
Additives for Polvmers
The new pigments come in three types: a rutile mixed metal oxide base provides colours such as brown and orange; a zinc oxide base gives light grey; and zinc sulphide is used to provide dark greens. Tests have been carried out in formulations with PVC, PP, LDPE, with good results, Sachtleben says. The pigments do not provide such good conductivity as conventional conducting pigments containing carbon black, the company believes, but it is confident that the conductivities produced are sufficient for the types of antistatic applications requiring such products.
BHT antioxidant from Thomas&van
Thomas Swan 8~Co. Ltd. of Consett, Co. Durham, (UK),
manufacturer of speciality chemicals, has introduced BHT (2,6 di tert butyl4-methyl phenol), an antioxidant with wide application in the polymer industry. The material is supplied as a homogeneous white crystalline powder with a minimum purity of 98%. It is soluble in white oil (0.5% wt) and at between 20 and 45% in a variety of solvents. It is insoluble in water. Information on antioxidant BHT is available from: Thomas Swan & Co. Ltd., Crookhall Works, Corlsett, Co. Durham DH8 7ND, UK. Tel: (0207j 505131 Telex: 53565 Fax 590467
Clarifying additive approved for food contact applications
The Health Protection Branch of the Canadian Bureau of Chemical Safety recently approved Milliken Chemical ’ s Millad 3905 polyolefme-clarifying additive for use in food contact applications. Since being introduced in 1980, the additive has been cleared for such applications by the US Food and Drug Administration, and by most European and Far Eastern countries. Polyolefins, particularly PP and LDPE, clarified with the additive are said to exhibit lower haze, improved gloss and good surface smoothness.
