New Polymer Formulations and Innovations – A Trending Phenomena in Polybutylene Terephthalate (PBT) Marketplace
The PBT marketplace continues to witness introduction of new polymer formulations or innovative integration of PBT with other materials. A number of PBT providers have introduced new polymer formulations with improved characteristics and at affordable costs.
Read Report Overview:
- In October 2017, BASF developed an Ultradur® – a polybutylene terephthalate (PBT) for PVC windows wherein PBT replaces steel and acts as a stiffening agent that deliver comparable strength as that of steel at an effective cost.
- In November 2017, DSM announced addition of hydrolysis-resistant grades of PBT to its Arnite® family of the thermoplastic polyester. The new introduction was aimed at providing an affordable solution for the application with exposures to humidity and high temperature such as automotive sensors, connectors and control devices.
- In October 2018, LAXNESS announced the expansion of its product range of halogen-free flame-retardant PBT compounds to include variants with outstanding fire resistance in glow wire tests. The new product range is reinforced with 25% glass fiber and the company is planning to introduce product trials in the market soon.
- DuPont Transportation & Advanced Polymers is planning to introduce a new Crastin® thermoplastic PBT polyester resins for high voltage EV/HEV connectors in October 2018. The new introduction is a fully-colored-compounded product that accommodates evolving automotive OEM requirements in EVs and HEVs.
R&D Investments Center around Development of Biodegradable Polybutylene Terephthalate (PBT) Polymer
As a sustainable alternative to petroleum-based plastics, development of bio-based plastics is the platform where a bulk of R&D investment is focused. In the PBT marketplace, research and developments activities are aimed at making PBT greener by increasing more bio-based content and efficient with the incorporation of innovative formulations.
As PBT applications range from automotive and electronics to other plastic-based uses, associated environmental concerns and increasing demand for bio-based solutions have led PBT manufacturers to ramp up efforts to devise biodegradable and renewable forms of PBT. Chemical industry titans such as DSM, DuPont and BASF have introduced bio-based PBT polymers equally efficient as their synthetic counterparts for multiple applications.
