Description:
PMMA is commonly known as plexiglass, acrylic, etc. The chemical name is polymethyl methacrylate. Due to the disadvantages of low surface hardness, easy rubbing, low impact resistance, and poor molding flow properties of PMMA, the modification of PMMA has appeared one after another. Such as the copolymerization of methyl methacrylate with styrene and butadiene, the blending of PMMA and PC, etc. 372 plexiglass is obtained by the copolymerization of methyl methacrylate and styrene. If a small amount of nitrile rubber (about 50%) is added to 372 plexiglass, 373 plexiglass can be obtained. The flow of PMMA is worse than that of PS and ABS, and the melt viscosity is more sensitive to changes in temperature. During the molding process, the melt viscosity is mainly changed from the injection temperature. PMMA is an amorphous polymer with a melting temperature greater than 160°C and a decomposition temperature of 270°C.
Treatment of plastics
PMMA has a certain water absorption, and its water absorption rate is 0.3-0.4%, and the injection molding temperature must be below 0.1%, usually 0.04%. The presence of water makes the melt appear bubbles, gas streaks, and reduce transparency. So it needs to be dried. The drying temperature is 80-90 ℃, and the time is more than 3 hours. In some cases, 100% of recycled materials can be used. The actual amount depends on the quality requirements, usually more than 30%. Recycled materials should avoid pollution, otherwise it will affect the transparency and the properties of the finished product.

Materials used for injection molding
All thermoplastics can be injection molded. Some thermosets and liquid silicones are also compatible with the injection molding process.
They can be also reinforced with fibers, rubber particles, minerals or flame retardant agents to modify their physical properties. For example fiberglass can be mixed with the pellets at ratios of 10%, 15% or 30% resulting in parts with higher stiffness. We list here several commonly used injection molding materials for reference.
Polypropylene (PP)
The most common Injection molding plastic. Excellent chemical resistance. Food-safe grades available. Not suitable for mechanical applications.
ABS
Common thermoplastic with high impact resistance, low-cost & low density. Vulnerable to solvents.
Polyethylene (PE)
Lightweight thermoplastic with good impact strength & weather resistance. Suitable for outdoor applications.
Polystyrene (PS)
The Injection molding plastic with the lowest cost. Food-safe grades available. Not suitable for mechanical applications.
Polyurethane (PU)
Thermoplastic with high impact strength and good mechanical properties & hardness. Suitable for molding parts with thick walls.
Nylon (PA 6)
Engineering thermoplastic with excellent mechanical properties and high chemical & abrasion resistance. Susceptible to moisture.
Polycarbonate (PC)
The plastic with the highest impact strength. High thermal resistance, weather resistance & toughness. Can be colored or transparent.
PC/ABS
Blend of two thermoplastics resulting in high impact strength, excellent thermal stability, and high stiffness. Vulnerable to solvents.
POM (Acetal/Delrin)
