Selecting Plasticizers for Adhesives and Sealants
Resistance to water, chemicals, UV, weathering, dirt, microorganisms & general aging Toxicity Cost analysis (volume required or plasticizing efficiency, price/pound, etc.) Learn How to Select the Plasticizer According to the Following Parameters: 1. Base Polymer Almost all types of polymers can be plasticized.
The UV resistance of adipate based polymeric plasticizers
These polyester plasticizers offer increased permanence over DOA. The focus of this paper is to demonstrate how adipate plasticizers, starting with DOA and increasing in molecular weight, affect the performance of flexible vinyl, especially in regard to UV resistance and permanence.
Palatinol DPHP
Palatinol DPHP. This plasticizer provides excellent weathering resistance properties for outdoor applications. The product’s high UV stability is complemented by its low odor characteristics, making it ideal for automotive interior applications and standard cable formulations. Its low volatility results in minimal fogging, which is a
Migration resistant polymeric plasticizer for poly(vinyl
Linear and branched poly (butylene adipate)s (PBA) with molecular weights ranging from 2000 to 10,000 g/mol, and a branching agent content between 0 and 1.8%, were solution cast with poly (vinyl chlo… 90 New PVC materials for medical applications—the release profile of PVC/polycaprolactone–polycarbonate aged in aqueous environments M.

Mechanical, chemical, and bio-recycling of biodegradable
This approach could be a significant breakthrough in the recycling of PHB waste to renewed PHB, improving the EOL management of PHB waste without downgrading the polymer. PBS is a partially bio-based polymer produced from bio-based succinic acid and fossil fuel-based 1,4-butanediol and it has gained significant interest in recent decades.
- Is adipate a good plasticizer?
- The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the glass-transition temperature was 132.2 °C in relation to pure PVC and 7.7 °C in comparison to compounds based on DOP.
- What is the molecular weight of poly (butylene adipate)?
- Linear and branched poly (butylene adipate)s (PBA) with molecular weights ranging from 2000 to 10,000 g/mol, and a branching agent content between 0 and 1.8%, were solution cast with poly (vinyl chloride) (PVC) to form 50‐ to 60‐μm thick flexible films.
- Can polymeric UV-absorber be used to stabilize PVC against UV irradiation?
- They showed great resistance to UV irradiation (200 h) without photodegradation while no small molecule was released. Most importantly, the polymeric UV-absorber is compatible with PVC and could be used as additive to stabilize PVC against UV-photoaging without degradation even after 200 h of UV irradiation.
- Does phenoxyethyl adipate plasticize PVC?
- The study of the rheological characteristics of PVC compounds containing butyl phenoxyethyl adipate showed that the developed plasticizer has a pronounced plasticizing effect in relation to PVC, which consists of a significant increase in the melt flow of PVC compounds in the temperature range of 160–205 °C.
- Can adipic acid ester be used as a PVC plasticizer?
- The purpose of this work is the synthesis of adipic acid ester and the study of the possibility of its use as a PVC plasticizer. The resulting butyl phenoxyethyl adipate was characterized by Fourier-transform infrared spectrometry, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).
- How does 50 ppm plasticizer adipate affect glass-transition temperature?
- The introduction of polyvinyl chloride 50 ppm plasticizer DOP led to a decrease in the glass-transition temperature of the polymer to −37 °C, that is, by 124.5 °C. A significant decrease in the Tgt parameter was observed when 50 ppm is introduced into the polymer. The synthesized adipate totaled 133.2 °C. 4.8.
