  • PBT

    PBT PET Alloy

    There are many differences in processing and applications between polyethylene terephthalate and polybutylene terephthalate due to the difference in crystallization behavior. Due to the high glass transition temperature and cold crystallization temperature of PET, its application range is limited. The rapid crystallization, toughening and reinforcement of PET must be solved to become a more valuable engineering plastic. The rapid crystallization of PET can reduce the injection molding cycle. PET alloys and the use of nucleating agents in the alloys were developed to improve the disadvantage of slow crystallization.

  • Introduction

    Introduction of Flame Retardant Brominated Epoxy Resin

    In a narrow sense, a flame retardant is a kind of flame retardant additive for polymer materials. It is originally a flammable or combustible polymer material. After adding this flame retardant additive, it can become a flame retardant material. Flame retardant can be divided into There are two types of additive type and reactive type. Additive flame retardants are added in the post-treatment or molding process of polymer materials, and generally do not chemically react with polymer materials, such as octabromoether and antimony trioxide. The typical reactive flame retardant is used as a monomer to participate in the polymerization reaction of polymer materials. For example, in the polymerization reaction of ordinary epoxy resin, the brominated epoxy resin bisphenol A type epoxy end polymerized with tetrabromobisphenol A is used. The bromine content of the brominated epoxy resin flame retardant increases with the increase of the molecular weight, but the increase decreases with the increase of the molecular weight, the minimum is 48.8%, and the maximum limit is 53.3%.

  • Polycaprolactone

    Polycaprolactone Review

    Polycaprolactone (PCL) is a semi-crystalline polymer that is a linear polymer obtained by ring-opening polymerization of E-caprolactone. PCL has a Tg of -60°C and a melting point of about 60°C. Due to the flexibility of its structure, the strength is insufficient. Therefore, it is necessary to modify PCL. Through the modification of PCL, a variety of new polycaprolactone materials can be constructed that can meet the requirements of existing or improved processing technology and can achieve specific functional requirements.

  • Polymer

    Polymer Chain Extension Research

    The lower molecular weight polymer obtained by the general polymerization method is about 20,000 or less, and the relative viscosity is low, while the relative viscosity of the resin used in engineering plastics is relatively high. Therefore, the research and development of high molecular weight polymers has become the main goal of scientific research. Polymers will inevitably produce a certain amount of waste in the production of plastic profiled materials. Generally speaking, recycled raw materials are obtained through the recovery, crushing and re-granulation of waste polymers. In the process of recycling and granulation, the tensile strength and viscosity of the recycled materials are greatly reduced due to the aging, pollution, and water absorption of the polymer. Therefore, in order to obtain high-performance materials, people have been researching and developing. One is to increase the relative molecular weight through polycondensation, and the other is to increase the viscosity through blending modification methods such as grafting, crosslinking, and chain extension.

    Research on Polycarbonate

    Polycarbonate, often abbreviated as PC, is a linear carbonated polyester. As a very representative aviation polymer material, it has very important application value and research significance. From the chemical point of view, PC is resistant to weak acids, weak bases, and neutral oils, but it is not resistant to ultraviolet light and strong bases. In terms of physical properties, PC is almost colorless, transparent, and has good optical properties. The density is about 1.20g/cm3, and the glass transition temperature is about 135°C.
