𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀 𝘁𝗵𝗮𝘁 𝗠𝗮𝘁𝘁𝗲𝗿 — 𝗣𝗣 (𝗣𝗼𝗹𝘆𝗼𝗹𝗲𝗳𝗶𝗻𝘀)

𝗦𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 | 𝗣𝗿𝗼𝗽𝗲𝗿𝘁𝗶𝗲𝘀 | 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 | 𝗗𝗼𝘄𝗻𝘀𝗶𝗱𝗲 | 𝗦𝗽𝗼𝘁𝗹𝗶𝗴𝗵𝘁: Mitsui Chemicals Europe


#𝗣𝗣 (𝗽𝗼𝗹𝘆𝗽𝗿𝗼𝗽𝘆𝗹𝗲𝗻𝗲) is a semi-crystalline 𝗰𝗼𝗺𝗺𝗼𝗱𝗶𝘁𝘆 𝘁𝗵𝗲𝗿𝗺𝗼𝗽𝗹𝗮𝘀𝘁𝗶𝗰 𝗽𝗼𝗹𝘆𝗺𝗲𝗿 synthesized from propylene monomers, forming a 𝗹𝗶𝗻𝗲𝗮𝗿 𝗰𝗵𝗮𝗶𝗻 𝗼𝗳 𝘀𝗮𝘁𝘂𝗿𝗮𝘁𝗲𝗱 𝗵𝘆𝗱𝗿𝗼𝗰𝗮𝗿𝗯𝗼𝗻 𝘂𝗻𝗶𝘁𝘀 𝘄𝗶𝘁𝗵 𝗺𝗲𝘁𝗵𝘆𝗹 𝘀𝗶𝗱𝗲 𝗴𝗿𝗼𝘂𝗽𝘀.



Its non-polar structure gives it 𝗲𝘅𝗰𝗲𝗹𝗹𝗲𝗻𝘁 𝗰𝗵𝗲𝗺𝗶𝗰𝗮𝗹 𝗿𝗲𝘀𝗶𝘀𝘁𝗮𝗻𝗰𝗲, 𝗹𝗼𝘄 𝗱𝗲𝗻𝘀𝗶𝘁𝘆 (~𝟬.𝟵𝟬 𝗴/𝗰𝗺𝟯), 𝗮𝗻𝗱 𝗵𝗶𝗴𝗵 𝗳𝗮𝘁𝗶𝗴𝘂𝗲 𝘀𝘁𝗿𝗲𝗻𝗴𝘁𝗵, particularly in cyclic loading. It also exhibits 𝗹𝗼𝘄 𝗺𝗼𝗶𝘀𝘁𝘂𝗿𝗲 𝗮𝗯𝘀𝗼𝗿𝗽𝘁𝗶𝗼𝗻 𝗮𝗻𝗱 𝗴𝗼𝗼𝗱 𝗱𝗶𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰 𝗽𝗿𝗼𝗽𝗲𝗿𝘁𝗶𝗲𝘀, making it suitable for electrical and fluid-contact parts.


PP is widely used in 𝗮𝘂𝘁𝗼𝗺𝗼𝘁𝗶𝘃𝗲 𝗶𝗻𝘁𝗲𝗿𝗶𝗼𝗿𝘀, 𝗽𝗮𝗰𝗸𝗮𝗴𝗶𝗻𝗴, 𝗰𝗼𝗻𝘀𝘂𝗺𝗲𝗿 𝗴𝗼𝗼𝗱𝘀, 𝘁𝗲𝘅𝘁𝗶𝗹𝗲𝘀 (𝗻𝗼𝗻𝘄𝗼𝘃𝗲𝗻𝘀), 𝗮𝗻𝗱 𝗽𝗶𝗽𝗶𝗻𝗴, where 𝗹𝗼𝘄 𝗰𝗼𝘀𝘁, 𝗲𝗮𝘀𝘆 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴, 𝗮𝗻𝗱 𝗲𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁𝗮𝗹 𝗿𝗲𝘀𝗶𝘀𝘁𝗮𝗻𝗰𝗲 are more critical than high mechanical performance. The following photo is a demonstrator drone made entirely out of carbon reinforced PP.


Its main weakness is its 𝗿𝗲𝗹𝗮𝘁𝗶𝘃𝗲𝗹𝘆 𝗹𝗼𝘄 𝘀𝘁𝗶𝗳𝗳𝗻𝗲𝘀𝘀 𝗮𝗻𝗱 𝘁𝗵𝗲𝗿𝗺𝗮𝗹 𝗿𝗲𝘀𝗶𝘀𝘁𝗮𝗻𝗰𝗲 (softening near 100–110 °C), which limits use in structural or high-heat environments, however 𝗿𝗲𝗶𝗻𝗳𝗼𝗿𝗰𝗶𝗻𝗴 𝘁𝗵𝗲 𝗣𝗣 𝗺𝗮𝘁𝗲𝗿𝗶𝗮𝗹 𝘄𝗶𝘁𝗵 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗼𝘂𝘀 𝗰𝗮𝗿𝗯𝗼𝗻 𝗳𝗶𝗯𝗲𝗿𝘀 can therefore significantly improve the stiffness limitation.


PP 𝗨𝗗-𝗧𝗮𝗽𝗲 reinforced with 𝗰𝗮𝗿𝗯𝗼𝗻 𝗳𝗶𝗯𝗲𝗿𝘀 can be procured from 𝗠𝗶𝘁𝘀𝘂𝗶 𝗖𝗵𝗲𝗺𝗶𝗰𝗮𝗹𝘀 𝗘𝘂𝗿𝗼𝗽𝗲 𝗚𝗺𝗯𝗛 (𝗠𝗖𝗘). Headquartered in 𝗗𝘂𝘀𝘀𝗲𝗹𝗱𝗼𝗿𝗳, 𝗚𝗲𝗿𝗺𝗮𝗻𝘆, MCE offers advanced thermoplastic composites under the 𝗧𝗔𝗙𝗡𝗘𝗫™ brand. These continuous fiber-reinforced polypropylene (PP) tapes and laminates are engineered for 𝗹𝗶𝗴𝗵𝘁𝘄𝗲𝗶𝗴𝗵𝘁 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲, 𝗿𝗲𝗰𝘆𝗰𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆, 𝗮𝗻𝗱 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴 𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝗰𝘆, making them a key part of Mitsui’s portfolio of functional materials.

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...
