Polymers | Free Full-Text | Preparation of Biomass-Based Ester End
Plasticizers with a lower relative molecular mass, less of a ring-like chemical structure, more ether chains and short alkyl chains have higher plasticizing efficiency [33,34]. The addition of plasticizer can decrease the interaction force between polymer molecules and increase the mobility of polymer chains.

Most of the acrylics require a plasticizer to achieve low temperature performance. Many monomerics are too volatile to be of value because of the post cure requirement. Low temperature performance can be best achieved with polymerics as well as TP-759 and TegMeR 812. APPLICATIONS . O-rings; Valve stem oil deflectors; Lip seals, gaskets
Calcium sulfate whisker modified polyvinylalcohol composite material
The composite material is prepared by the following materials according to part by weight: 70 to 90 portions of polyvinyl alcohol, 10 to 20 portions of calcium sulfate whisker with the diameter of 10 to 20 Mum, 1 to 3 portions of surface modifier, 1 to 5 portions of plasticizer, and 0.5 to 1.5 portions of lubricant.

determines the choice of plasticizer, chosen so as to resist volatilization during the heat aging tests needed to qualify. Loss of plasticizer is the major cause of decreased elongation after heat aging. For service in dry locations, most such compounds use calcium carbonate (CaCO 3) ller. The level is adjusted to balance material cost
Synergistic Effects of Nucleating Agents and Plasticizers on the
The synergistic effect of nucleating agents and plasticizers on the thermal and mechanical performance of PLA nanocomposites was investigated with the objective of increasing the crystallinity and balancing the stiffness and toughness of PLA mechanical properties. Calcium carbonate, halloysite nanotubes, talc and LAK (sulfates) were compared with each other as heterogeneous nucleating agents
