LG Chemical IH830 PMMA

Product Overview

LG Chemical IH830 is a general-purpose injection-grade transparent polymethyl methacrylate (PMMA, acrylic) raw material introduced by LG Chemical (South Korea). Supplied in the form of cylindrical transparent pellets, the product features ultra-high light transmittance, extremely low haze, and a low yellowing tendency, making it a globally widely used optical-grade injection PMMA grade.

This base resin balances rigidity, surface hardness, and molding processability, featuring moderate melt flowability and adaptability to mainstream injection molding processes. Backed by stable optical performance and balanced mechanical properties, it is widely applied in optical components, consumer electronics transparent windows, lighting accessories, instrument cover plates, and other fields, earning high recognition from transparent plastic product manufacturers both domestically and internationally. ZiJun Plastics offers genuine, original-factory stock supply of LG Chem IH830 PMMA, accompanied by complete original technical documentation, supporting sample requests and bulk export orders.

Features & Benefits

• Excellent Optical Quality: Light transmittance reaches up to 92.0%, haze is as low as 0.50%, and the yellowness index is only 0.40. Molded products are clear and clean, and less prone to noticeable yellowing during long-term use, meeting the requirements for most transparent exterior parts and basic optical accessories.

• High Rigidity and Surface Hardness: Rockwell hardness of M98 with balanced tensile and flexural strength performance. Finished product surfaces are wear-resistant and less susceptible to scratches, reducing the risk of exterior damage.

• Stable Molding Dimensional Control: Flow-direction shrinkage ranges from 0.20% to 0.60% with a narrow range, helping precision transparent plastic parts maintain tight dimensional tolerances and reducing warpage and deformation.

• Moderate Flowability with Friendly Processing Window: Stable melt flow rate performance suitable for conventional injection molding equipment, capable of producing medium-wall-thickness transparent products with low process optimization difficulty.

• Good Weathering Resistance: Pure PMMA base resin naturally possesses superior UV resistance, resulting in slower aging and discoloration rates outdoors compared to standard general-purpose plastics.

Applications

1. Lighting Industry: LED lamp shades, lighting translucent outer shells, decorative light guide accessories, and flat transparent panels.

2. Consumer Electronics Accessories: Equipment transparent windows, display protective cover plates, and small digital product decorative transparent shells.

3. Instrumentation Field: Instrument dial faces, observation windows, scale panels, and optical nameplates.

4. Housewares & Gift Industry: Transparent crafts, display stands, and cosmetic transparent packaging shells.

5. Automotive Interior Accessories: In-vehicle light-transmissive decorative parts, logo cover plates, and small interior transparent decorative components.

Note: This grade has a flame rating of HB and is not suitable for electrical components with strict flame retardancy requirements.

Frequently Asked Questions (FAQs)

Q1: Is pre-drying required before processing LG Chemical IH830 PMMA? What are the recommended drying parameters?

A: PMMA material is hygroscopic. If the raw material absorbs moisture, injection molding can easily produce bubbles and silver streak defects. Recommended drying conditions: 80~90°C hot air drying for 3~4 hours, controlling moisture content below 0.05% after drying. Keep sealed and insulated as much as possible after drying to prevent reabsorbing moisture from the air.

Q2: How should a selection be made between LG IH830 PMMA and PC transparent materials?

A: The advantages of IH830 PMMA lie in superior light transmittance, higher surface hardness, and lower cost; its disadvantages are lower impact strength and a lower upper temperature limit compared to PC. If the product prioritizes exterior light transmission, operates under a limited budget, and lacks high-impact resistance requirements, IH830 is preferred. If the product needs to withstand impact or long-term high-temperature working conditions, PC material is recommended.

Q3: Does LG Chemical IH830 PMMA meet RoHS and REACH export compliance requirements? Can related documents be provided?

A: The raw LG Chemical IH830 base resin complies with RoHS and REACH control standards. ZiJun Plastics can provide original COA, MSDS, and TDS documents upon shipment to support overseas export customs clearance; third-party testing reports can also be arranged upon request.

Q4: Is IH830 PMMA suitable for extrusion or injection molding?

A: IH830 is positioned as an injection-grade PMMA, with its flowability and thermal properties primarily tailored for injection molding processes; it is not recommended for large-scale sheet or film extrusion. If a dedicated extrusion grade is required, we suggest consulting other extrusion-specific models.
