Plastic raw material is a key factor in determining product quality, and the formula also affects product performance, so the formula analysis of plastics is very critical. Noah's third-party testing agency will start testing from the aspects of product matching, dosage, mixing and material selection. Noah's testing experts explained that these four elements are complex and diverse, including many connections. Based on years of testing and testing experience, Noah Test can provide one-stop plastic formula testing services.
Noah detection Plastic formula analysis —Raw resin selection
(1) Selection of resin varieties
Noah detection experts recommend that resins should be selected that have the closest performance to the modification purpose to save the amount of additives added. For example, wear-resistant modification, the resin should first consider choosing three major wear-resistant resins PA, POM, and UHMWPE; for example, transparent modification, the resin should first consider choosing three major transparent resins PS, PMMA, and PC.
(2) Selection of resin fluidity
The viscosity of various plasticized materials in the formula should be close to ensure processing fluidity. Noah's testing agency said that for materials with huge viscosity differences, transition materials should be added to reduce the viscosity gradient. For example, PA6 is often added as the transition material in the PA66 toughening and flame retardant formula, and HDPE is often added as the transition material in the PA6 toughening and flame retardant formula.
The same type of plastic also has different fluidity. The main reason is the different molecular weight and molecular chain distribution, so the same raw material is divided into different grades. According to the different flowability required for different processing methods, Noah's inspection divides the grades into injection molding grades, extrusion grades, blow molding grades, calendering grades, etc.
Through the above content, you can understand the importance of raw materials and formulas. The plastic formula analysis team of Noah Testing Agency has rich industry formula design and testing experience, and can provide corresponding solutions to corporate problems. At the same time, it designs product formulas that are simple to operate, cost-effective and outstanding in performance for the company.
