Plasticizers. Plasticizers ensure elasticity and flexibility of polymer materials. But this is not their only benefit. Plasticizers also optimize, for example, the processing properties of polymer materials, which leads to improved product quality or even new properties. The choice of plasticizers depends on the demand placed on the finished
Plastic Additives
The most common plasticizers are phthalatic, trimellitic, benzoic, and adipic acid esters. These low molecular weight compounds function as spacers between polymer chains and reduce the rotational energy barrier, thus improve the flexibility of the plastic.
Food additives: stabilizers, thickeners, and gelling agents
Widely-used stabilizers include agar, carrageenan and pectin, which are used in dairy products, dressings, syrups and mayonnaise. Thickeners Thickening agents increase the viscosity of food preparations without affecting other properties like taste. These agents include polysaccharides like starches and gums, or proteins like gelatin.
INTRODUCTION TO POLYMER ADDITIVES AND STABILIZATION - PQRI
Introduction Products of polymer degradation Stabilizers Relative Discoloration Extending Beyond Polymer Protection Chemistry of Phosphite Hydrolysis Good stabilization will reduce formation of aldehydes, ketones, and color bodies Some stabilizers, which can terminate alkyl radicals, are especially effective (vitamin E, lactone, hydroxyl amine)
- 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.
- How are plasticizers classified?
- Plasticizers are classified according to their molecular structure into monomeric or polymeric types. The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use.
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- What are plasticizers & modifiers?
- Plasticizers and Modifiers are part of the Polymer Additive Business Unit and comprise of a wide range of high-quality products under the brand names Mesamoll ®, Adimoll ®, Unimoll ®, Ultramoll ®, K-FLEX ®, Vitroflex ®, Modulast ®, Uniplex ®, Triacetin, Acetine, and Baymod®. Mesamoll ® is a phthalate-free universal monomeric plasticizer.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. 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.
