INTRODUCTION TO POLYMER ADDITIVES AND STABILIZATION - PQRI
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) Systems for gamma irradiation have been developed Systems for reduction of organoleptics from slip agents are under development

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
PVC Plasticizers and Stabilizers Following Safer Sustainable
VESTINOL 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window. ELATUR DPT (DiPentylTerephthalate) plasticizer has very low Volatile Organic Compound (VOC) residue build-up, has a low viscosity, and is fast fusing upon gelation.
Plastic Additives: Polymer Stabilizers, Plasticizers and
During the manufacturing of polymeric materials, such as plastics and rubbers, a number of chemical additives are added to inhibit or retard their degradation or to achieve better product quality. Heat stabilizers, antioxidant, UV absorber, plasticizers and lubricants are the most commonly seen and widely used additives.
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. Plasticizers also lower the processing temperature and change many other physical and
- What is a stabilizer & thickener?
- Common Additives: Xanthan gum, guar gum, and modified starches. Stabilizers and thickeners play a pivotal role in the food industry by enhancing product quality, safety, and consistency. They support a wide range of food categories, from dairy to frozen items, and cater to evolving consumer demands such as vegan and low-calorie products.
- What are some examples of stabilizers & thickeners?
- Examples: Baby purees, infant cereals, and baby formulas. Purpose: To ensure smooth texture, improve viscosity, and prevent separation of liquids and solids. Common Additives: Xanthan gum, guar gum, and modified starches. Stabilizers and thickeners play a pivotal role in the food industry by enhancing product quality, safety, and consistency.
- What are food thickeners?
- Food thickeners are compositionally and structurally complex materials and can exhibit a wide range of rheological properties at different concentrations and conditions. Stabilizers, emulsifiers, thickeners and gelling agents are more often simply referred to as food hydrocolloids in food industries.
- What is a thickening agent?
- None. Thickening agents or thickeners, are substances from different sources, which are widely used for modification of rheological and textural properties of food. Thickeners are one of the major food ingredients which significantly control the properties of food products.
- Which starch based thickeners are used in food applications?
- Some of the most commonly used starch based thickeners such as corn-starch, tapioca starch, and rice starch and newly searched underutilized plant extracts as thickening agents in food applications are discussed below. Table 3. Plant sources of thickening agents and their food applications. Chia (salvia hispanica l.) 3.3.1. Starch based
- Is mucilage a good thickening agent?
- Mucilage and plant polysaccharides are easily available and cheap food formulations. The medicinal attributes and functionality in rheology, make foods fortified with A. homolocarpum a good candidate for thickening agent with higher consumer acceptance.
