Surfactants can also be used to clean plastic surfaces. Liu Yali] studied cleaning agents for plastic surfaces. The cleaning agent is composed of Las (sodium dodecylbenzene sulfonate), TX (octylphenol polyoxyethylene ether) and Ta (polyether non-ionic surfactant). It has good cleaning effect on ABS, PVC, PP and phenolic plastics.

CaCO3 modified by surfactant can be filled in plastic and greatly improve its processability and mechanical properties. Ji Hongnian synthesized alkyl phosphate esters with different carbon chain lengths and used them for the modification of light calcium carbonate. When the dosage is 2.5% (modifier / calcium carbonate mass ratio), the surface properties and filling properties of plastic filler CaCO3 can be significantly improved. The processability and mechanical properties of soft PVC system can be significantly improved, and the processability of single ester modification is better than that of double ester with the same carbon chain length.

In recent years, the development of polyurethane (PU) industry has been developing rapidly. This is because PU materials have excellent properties. Their soft foam plastics are characterized by light weight, softness, insulation, breathability, innocuity, good resilience, moisture resistance, aging resistance, organic solvents, sound insulation and thermal insulation. Therefore, they are widely used in transportation, construction, decoration, industrial equipment, pipeline insulation, light industry, civil furniture and other fields. Surfactant (mainly silicone surfactant) is one of the essential components in the foaming process of PU foam.

The PU foam stabilizer H-420 (silicone surfactant) has been synthesized in Jin Xin Wen. Its foam has the same properties as imported products. Yan Min synthesized silicone surfactant (low hydrogen polysiloxane and allyl terminated polyether as intermediates) and applied it to the production of PU Rigid Foam with good foam uniformity. Niax Silicone SE-232 (silicone surfactant) produced by Momentive Performance Materials abroad, Niax M-6682 (ester surfactant) can be used for the preparation of net PU foam plastics.
