Applications & Processing Guidelines
Typical Applications
Backed by its exceptional light transmittance, surface hardness, and mechanical properties, Mitsubishi Chemical Acrypet® VH-001 is widely used in the following end products and working environments:
- Optics & Electronics: LCD light guide plates, instrument cluster transparent panels, indicator lamp covers, and electronic product protective lenses.
- Automotive Industry: Automotive tail lamp covers, interior dashboard shields, decorative trims, and light-transmitting buttons.
- Construction & Consumer Goods: High-end lighting fixture light-transmitting covers, signage, advertising display stands, and various high-gloss consumer product structural parts.
Processing Guidelines
- Drying Treatment: PMMA possesses a certain level of moisture absorption. To prevent surface silver streaks, bubbles, or degradation during injection molding, thorough drying is required prior to processing. A hot-air circulation drying oven is recommended at 75-85 °C for 2-4 hours, keeping the moisture content below 0.05%.
- Injection Molding: The melt temperature is generally recommended to be controlled between 210-250 °C. Mold temperature directly affects internal stress, surface gloss, and shrinkage rate, and is recommended to be set at 60-80 °C. Standard screws should be used in the injection molding machine to prevent material decomposition caused by shear overheating.
- Molding Shrinkage: The parallel mold shrinkage rate for this grade ranges between 0.2%-0.6%. Mold design and dimensional tolerances should be precisely compensated based on specific wall thicknesses.
Logistics, Packaging & Compliance
- Packaging Specifications: Standard packaging utilizes 25 kg moisture-proof multi-layer composite paper bags or paper-plastic composite packaging lined with a high-density polyethylene moisture-proof film, effectively preventing moisture absorption during transit and storage. Bulk customer requirements can also be met with big bags or customized packaging services.
- Supply Attribute: This product belongs to non-hazardous chemicals (Non-DG) and complies with international general chemical raw material and engineering plastic transportation standards. It supports global shipping via sea freight (FCL/LCL), land freight, and air freight without requiring special hazardous material transportation qualifications.

We recommend the classified recycling and rational reuse of runner and sprue materials generated during production under compliant conditions to jointly promote low-carbon and sustainable development in the plastics industry.
FAQs
Q1: Must Mitsubishi Chemical Acrypet® VH-001 be dried prior to injection molding?
A1: Yes, strict drying is mandatory. Although PMMA has relatively low moisture absorption, excess residual moisture can easily cause surface silver streaks, bubbles, or molecular chain degradation during high-temperature injection molding, severely impacting optical transmittance and mechanical strength. It is recommended to dry at 75-85 °C for 2-4 hours.
Q2: Where do the primary optical advantages of this grade lie?
A2: VH-001 features exceptional optical purity, exhibiting a visible light transmittance (0.3 mm) of up to 92.5%, a haze of only 0.300%, and a refractive index of 1.49. This makes it exceptionally suited for applications with strict demands on optical performance, such as transparent optical parts, automotive lamp covers, and display panels.
Q3: How should shrinkage rates be considered during mold design for this material?
A3: VH-001 has a parallel mold shrinkage rate of 0.2%-0.6%. Since PMMA is a rigid amorphous polymer, its shrinkage rate is relatively low and stable; however, mold design still requires meticulous adjustments based on product wall thickness, gate placement, and cooling rates to avoid internal stress concentrations or warpage.
