POLYMERIC PLASTICIZER PERFORMANCE IN PVC FOAM - Hallstar Industrial
POLYMERIC PLASTICIZER PERFORMANCE IN PVC FOAM PVC foam manufacturers have historically used low molecular weight monomeric esters to plasticize their products. With higher performance expectations and new regulations, we believe there is an unmet need.
Effects of molecular design parameters on plasticizer performance
Abstract. Using all-atom molecular simulation, a wide range of plasticizers for poly (vinyl chlorid) (PVC), including ortho- and tere-phthalates, trimellitates, citrates, and various aliphatic dicarboxylates, are systematically studied. We focus on the effects of plasticizer molecular structure on its performance, as measured by performance
Plasticizer - an overview | ScienceDirect Topics
To make PVC flexible at least 15 phr plasticizer is required. Less than this amount induces antiplasticization, and actually increases stiffness. Plasticizers can be used alone or in combination to get the desired properties such as tensile and tear strength or low temperature flexibility.
Eastman Plasticizers for PVC
Admex 523 is a low molecular weight, polymeric plasticizer. It is characterized by a mild ester odor and very light color. It imparts excellent processability to PVC compositions and is compatible with a wide variety of other polymers. Product availability by region: Asia Pacific | Latin America | North America
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- Why is PVC cm a good material for foaming?
- Due to good compatibility of PVC with PMDI and MHHPA, the PVC/CMs blend is homogeneous, where CMs act as a temporary plasticizer to increase PVC foamability by reducing its viscosity and increasing extendability during sc-CO2 foaming process. The PVC melt provided enough strength for realizing cell growth to give PVC/CMs foam.
- How permanent is a polymeric plasticizer in a flexible PVC compound?
- The permanence of a polymeric plasticizer in a flexible PVC compound depends upon three major factors which include structure, molecular weight/ viscosity, and polarity. Polymerics composed of branched structures are more permanent than those based upon linear structures.
- What is PVC/polyurea blend foam?
- PVC/polyurea blend foam shows excellent structural robustness and shape memory behavior. The blend foam has excellent thermal insulation performance due to ultra-high expansion ratio and small cell size. Polymer rigid foams are highly required in the fields of wind power, transportation and construction due to lightweight and high performances.
- Does PVC plastisol composition and processing conditions affect foam expansion and tear strength?
- Pilic, B. (2014) “Effect of PVC plastisol composition and processing conditions on foam expansion and tear strength,” Hemijska industrija. The quality of vinyl floorings depends mainly on the right control of the formation of poly (vinyl chloride) (PVC) foam structure.
- What is the difference between polymeric and monomeric plasticizers?
- th the PVC material. In short, polymeric plasticizers provide greater perman nce than monomerics. Polymeric and monomeric ester plasticizers can often be blended together. This imparts the best attributes of both classes, resulting in optimal performance in the
