Injection molding process of PPS material
Machining of PPS
PPS resin is highly machinable, allowing the manufacture of precise and complex parts:
Coolants: Non-aromatic, water-soluble coolants, such as pressurized air and spray mists, are ideal for achieving high-quality surface finishes and close tolerances.
Annealing: A temperature controlled annealing process is recommended to reduce surface cracks and internal stresses.
Extrusion
Drying conditions: Pre-drying at 121°C for 3 hours is fresh dataset recommended to ensure adequate moisture control.
Melting temperature: A melting temperature between 290 and 325°C is suitable for PPS extrusion.
Mold Temperature: Maintaining mold temperatures between 300 and 310°C is ideal for extrusion processes.
PPS recycling
PPS plastic is recyclable by mechanical and chemical methods:
Chemical recycling: Depolymerization and other chemical processes can break down PPS into its monomers for further polymerization.
Mechanical recycling: This involves crushing or shredding PPS waste into small pieces for reuse.
Despite the challenges posed by its high melting point and chemical resistance, specialized recycling facilities are equipped to handle PPS recycling, promoting a circular economy and sustainable practices.
Polymethyl methacrylate (PMMA), commonly known as acrylic, is a transparent thermoplastic often used as a lightweight, impact-resistant alternative to glass. Known for its clarity and durability, it has become a material of choice in a variety of industries, from automotive to medical devices. This guide takes a detailed look at PMMA plastic, its properties, applications, processing techniques, and material improvements to help designers and manufacturers take full advantage of this versatile material. So, without further ado, let’s dive deep into everything you need to know about designing and manufacturing acrylic products.
What is polymethyl methacrylate (PMMA)?
PMMA plastic is a synthetic polymer of methyl methacrylate. It is formed by mass polymerization, where methyl methacrylate monomers are combined with an initiator to create long polymer chains.
Acrylic is distinguished by its clarity, with a light transmission of over 90%, higher than that of glass. It is also known for its excellent resistance to weather, sunlight, rain and most chemicals.
