Professional R&D and excellent quality plasticizer chemicals

Ordinary polymer materials consist of many components such as matrix, filler, plasticizer, stabilizer and antioxidant. Heretofore, an important property of the polymer materials as a commercial product is its mechanical strength. However, the mechanical strength is not a sufficient index to consider the factor of degradation.

The results showed that the ZJ-I rejuvenator formulated with 83.6% extracted oil, 15% plasticizer DOP, 1.4% hydrogenated petroleum resin, 0.6% antioxidant, and 0.4% light stabilizer has the best regeneration effect, and its optimal dosing is 7% aging degree. It can also improve the adhesion performance of asphalt and aggregate. 1 Introduction

The increased interest in the development of bio-based plasticizers for PVC is related to the plasticizers synthesized from biorenewable plant oils (for example, rice fatty acid , soybean oil , hydrogenated castor oil, camphor , etc.), agricultural by-products (for example, sugar cane , glucose , etc.) and waste (for example, cooking oil [32, 33]).

The epoxidized rubber seed oil (EeRSO) was a mixture of epoxidized triglyceride, and epoxidized methyl ester of free fatty acids was used as a secondary plasticizer for PVC. An increase in tensile properties was observed by substituting the 10 phr DOP plasticizer with the EeRSO in PVC formulation. A leaching test was performed in five media to evaluate the plasticizing effect. The sample

of Joseph et al. indicated that epoxidized rubber seed oil could be used as a less volatile secondary plasticizer and heat stabilizer for PVC in combination with dioctyl phthal-ate (DOP) [9]. Zinc soaps of rubber seed oil and/or epoxi-dized rubber seed oil were used as thermal stabilizers for PVC plastigels by Egbuchunam et al., and the eect
