Product Overview

Wanhua Chemical CLARNATE® A1105 is a high-quality polycarbonate (PC) engineering plastic resin independently developed by the world-renowned advanced materials manufacturer, Wanhua Chemical. The product is supplied in standard pellet form and exhibits a colorless, highly clear/transparent visual characteristic in appearance.

As a medium-viscosity, general-purpose, injection molding grade PC material, CLARNATE® A1105 is well-known in the industry for its extremely balanced physical and mechanical properties as well as excellent processing stability. Wanhua Chemical utilizes an advanced interfacial polycondensation phosgene production process, which endows this grade with exceptionally high purity and outstanding easy release characteristics. In the current international engineering plastics market, A1105 has become an ideal choice in fields such as electrical and electronic housings, transparent household goods, premium consumer products, and food-contact containers (such as water bottles and baby bottles) to replace traditional transparent plastics (like PMMA, AS) or high-priced imported PC resins.

Features & Benefits

  • Crystal-Like Flawless Transparency (Optical Clarity): The light transmittance is up to 89%, and the haze is strictly controlled below 0.8%. Its excellent refractive index (1.586) and low impurity rate give the finished products a glass-like clear texture and premium visual gloss.

  • Excellent Impact Resistance & Mechanical Toughness (High Impact Strength): It inherits the strong and tough genetic traits of polycarbonate, widely known as “bulletproof plastic”. With a tensile strength of 72 MPa and an Izod notched impact strength as high as 800 J/m, it is highly resistant to cracking or breaking upon external intense collisions or drops, offering an extremely high safety factor.

  • Superb Mold Release & Injection Flowability (Easy Release & Good Processability): As a medium-viscosity grade, A1105 is specifically formulated with highly effective mold release components. It features a short molding cycle and is not prone to sticking to the mold after forming, which significantly reduces the defect rate of large, complex, or thin-walled transparent injection-molded parts.

  • Robust Heat Resistance & Dimensional Stability (Thermal & Dimensional Stability): The Vicat softening temperature reaches up to 150 °C, and the heat deflection temperature is 130 °C. Within a wide range of temperature fluctuations, the mold shrinkage rate remains as low as 0.5-0.7% and is extremely stable, making the finished products less prone to warpage or deformation.

Typical Applications

1. Premium Consumer Goods & Food Contact Containers

  • High-grade space cups, shatterproof sports water bottles.

  • Heat-resistant baby bottles, milk storage jars, and daily food preservation containers (utilizing its excellent heat resistance, high transparency, and resistance to repeated washing and cross-linking degradation).

2. Electronic & Electrical Appliance Enclosures

  • Smart home device housings, transparent panels, smartphone casings, and digital product protective shells.

  • Charger casings, LED lighting diffusers, and transparent protective covers for instrument panels.

3. Automotive Industry Components

  • Automotive interior transparent trim strips, interior reading light lenses, and ambient light light-guiding strips.

  • Automotive dashboard lenses and various heat-resistant, shatterproof structural components and brackets.

4. Medical & Industrial Protection (Medical & Industrial Glazing)

  • Medical vacuum blood collection tubes, non-sterile transparent medical vessels, and laboratory protective face shields.

  • Industrial equipment inspection windows and explosion-proof protective switch panels.

Frequently Asked Questions (FAQs)

1. What are the drying conditions for Wanhua Chemical PC A1105 prior to injection molding, and why is drying mandatory?

A: Polycarbonate (PC) is extremely sensitive to moisture traces. If the moisture content exceeds the limit, a hydrolysis reaction will occur during high-temperature injection molding, resulting in silver streaks and bubbles on the product surface, while severely degrading the material’s impact strength.

  • Recommended Drying Conditions: It is recommended to dry the material at 120 °C for 4 to 5 hours using a hot-air circulating dryer, or at 120 °C for 3 to 4 hours using a dehumidifying dryer.

  • Precautions: The hopper after drying should be kept sealed, and the material should be consumed as soon as possible after drying is complete. Avoid exposing the raw material to the air for more than 30 minutes to prevent secondary moisture absorption.

2. Compared to common transparent materials such as PMMA (Acrylic) and AS resin, what are the core advantages of CLARNATE® A1105?

A: Although PMMA and AS also possess excellent transparency, their fatal weaknesses are brittleness, lack of drop resistance, and low temperature resistance.

  • Impact Resistance: The impact strength of PC A1105 (800 J/m) is several to dozens of times that of PMMA. It is recognized as a “bulletproof plastic” and is extremely difficult to break when dropped.

  • Heat Resistance: The heat deflection temperature of A1105 is as high as 130 °C, whereas the service temperature of PMMA and AS can rarely exceed 80 – 90 °C. Therefore, for transparent products that require boiling water brewing, high-temperature drying, or have certain heat resistance requirements (such as baby bottles and electric kettle bodies), PC A1105 must be the premier choice.

3. Does this grade comply with international environmental and regulatory compliance certifications? What certificates can be provided?

A: Yes. As a first-tier international chemical giant, Wanhua Chemical ensures that its CLARNATE® A1105 carries comprehensive global compliance certifications. The material fully complies with the EU RoHS directive (Restriction of Hazardous Substances) and REACH regulations (Substances of Very High Concern – SVHC testing standards). Its flame-retardant performance achieves a standard UL 94 V2 rating at 1.5mm and a UL 94 HB rating at 3.0mm. Depending on specific batches and procurement requirements, Wanhua’s official channels and authorized first-tier distributors can fully cooperate to provide the original Certificate of Analysis (COA), Safety Data Sheet (SDS), and corresponding declarations of conformity.
