𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀 𝘁𝗵𝗮𝘁 𝗠𝗮𝘁𝘁𝗲𝗿 — 𝗣𝗣𝗦 (𝗣𝗼𝗹𝘆𝗽𝗵𝗲𝗻𝘆𝗹𝗲𝗻𝗲 𝗦𝘂𝗹𝗳𝗶𝗱𝗲𝘀)

𝗦𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 | 𝗣𝗿𝗼𝗽𝗲𝗿𝘁𝗶𝗲𝘀 | 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 | 𝗗𝗼𝘄𝗻𝘀𝗶𝗱𝗲 | 𝗦𝗽𝗼𝘁𝗹𝗶𝗴𝗵𝘁: Teijin Carbon


#𝗣𝗣𝗦 is a semi-crystalline, high-performance 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝘁𝗵𝗲𝗿𝗺𝗼𝗽𝗹𝗮𝘀𝘁𝗶𝗰 consisting of a 𝗹𝗶𝗻𝗲𝗮𝗿 𝗮𝗿𝗼𝗺𝗮𝘁𝗶𝗰 𝗯𝗮𝗰𝗸𝗯𝗼𝗻𝗲 𝘄𝗶𝘁𝗵 𝗮𝗹𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝗻𝗴 𝗯𝗲𝗻𝘇𝗲𝗻𝗲 𝗮𝗻𝗱 𝘀𝘂𝗹𝗳𝗶𝗱𝗲 𝗹𝗶𝗻𝗸𝗮𝗴𝗲𝘀.



This structure provides 𝗲𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻𝗮𝗹 𝗰𝗵𝗲𝗺𝗶𝗰𝗮𝗹 𝗿𝗲𝘀𝗶𝘀𝘁𝗮𝗻𝗰𝗲, 𝗳𝗹𝗮𝗺𝗲 𝗿𝗲𝘁𝗮𝗿𝗱𝗮𝗻𝗰𝘆, 𝗮𝗻𝗱 𝗱𝗶𝗺𝗲𝗻𝘀𝗶𝗼𝗻𝗮𝗹 𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆, even in aggressive thermal and chemical environments. Its tightly packed aromatic chains and high crystallinity result in 𝗵𝗶𝗴𝗵 𝘀𝘁𝗶𝗳𝗳𝗻𝗲𝘀𝘀 𝗮𝗻𝗱 𝗲𝘅𝗰𝗲𝗹𝗹𝗲𝗻𝘁 𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰𝗮𝗹 𝗶𝗻𝘀𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗽𝗿𝗼𝗽𝗲𝗿𝘁𝗶𝗲𝘀, with minimal creep under load.


PPS is commonly used in 𝗽𝘂𝗺𝗽 𝗵𝗼𝘂𝘀𝗶𝗻𝗴𝘀, 𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰𝗮𝗹 𝗰𝗼𝗻𝗻𝗲𝗰𝘁𝗼𝗿𝘀, 𝗣𝗖𝗕 𝗰𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀, 𝗮𝗻𝗱 𝗳𝗹𝘂𝗶𝗱 𝗵𝗮𝗻𝗱𝗹𝗶𝗻𝗴 𝘀𝘆𝘀𝘁𝗲𝗺𝘀, where chemical resistance and thermal stability are critical, often up to 200 °C continuous use. Pictured below are 𝘁𝗶𝗲 𝗿𝗼𝗱𝘀 made from PPS UD tape and injection molded materials.


Its primary weakness is 𝗯𝗿𝗶𝘁𝘁𝗹𝗲𝗻𝗲𝘀𝘀, especially in unfilled or unmodified grades, which limits its impact strength without fiber reinforcement or toughening agents.


𝗣𝗣𝗦 𝗨𝗗-𝗧𝗮𝗽𝗲𝘀 reinforced with carbon fibers can be procured from 𝗧𝗲𝗶𝗷𝗶𝗻 𝗖𝗮𝗿𝗯𝗼𝗻 𝗘𝘂𝗿𝗼𝗽𝗲. Teijin Carbon has their 𝘁𝗮𝗽𝗲 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗹𝗼𝗰𝗮𝘁𝗲𝗱 𝗶𝗻 𝗛𝗲𝗶𝗻𝘀𝗯𝗲𝗿𝗴, 𝗚𝗲𝗿𝗺𝗮𝗻𝘆 and is subsidiary of Teijin Limited. Teijin Limited is headquartered in Tokyo, Japan, and is one of the world’s leading suppliers of 𝗵𝗶𝗴𝗵-𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 𝗳𝗶𝗯𝗲𝗿𝘀, including Tenax® carbon fiber, which is widely used in aerospace, automotive, and industrial composite applications.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
