What is PC PBT 1102

In the current era of accelerated upgrading in the manufacturing industry, materials not only need to withstand impacts and chemical corrosion but also remain stable in low temperatures, outdoors, and at the pace of mass production. The PC+PBT 1102 from SABIC is precisely designed for this kind of "complex working conditions + large-scale production" : it strikes a balance between cold resistance and fluidity, and performs stably in the automotive, electronic and electrical, home appliance and industrial equipment fields.

01 | Product Highlights

All-weather reliable: During winter road tests, installation in cold regions, or long-term outdoor exposure, the parts remain resilient at -30°C and do not crack.

Chemical resistance for greater peace of mind: Its performance is less likely to decline when exposed to media such as fuel, lubricating oil, alcohols, and alkaline cleaning solutions. Suitable for the periphery of engine compartments, the enclosures of charging and distribution equipment, and industrial panels.

Dual balance of strength and size: Sufficient rigidity and stable impact; The low shrinkage rate (about 0.8-1%) brings better assembly consistency and appearance stability.

Processing-friendly and controllable for mass production: The granular material is ready to use on the machine, has moderate fluidity, can smoothly fill molds even in complex cavities, and has controllable warpage, making it suitable for multi-mold cavities and rhythmic production.

Basic flame retardancy: UL94 HB, covering the basic safety requirements of most electronic enclosures and connectors.

02 | Typical Applications

Automobiles: Headlight housings, air intake grilles, sensor brackets, wiper system components, external camera/radar housings - they should be both aesthetically pleasing and weather-resistant.

Electronic and electrical/new energy: Charging gun and charger housing, circuit breaker/terminal, control panel - there are synchronous requirements for structural strength and surface quality.

Consumer and Industrial: Power tool housings, sports equipment, pump and valve/gear guards, medium resistant equipment panels - durability and dimensional consistency are given more emphasis.

03 | Key Points of Processing Technology

Drying: Thoroughly dry before molding to reduce the risk of silver streaks, air streaks and weld marks.

Температура формы: It is recommended to start from 60-80°C. For thin-walled and high-appearance parts, the upper limit should be given priority, taking into account both smoothness and rhythm.

Filling/pressure holding: Medium to high injection speeds are adopted in combination with segmented pressure holding to stabilize the leading edge of the melt, reducing shrinkage and joint marks. The holding time and pressure can be fine-tuned according to the wall thickness.

Exhaust and gate: Ensure smooth exhaust on the parting surface and gate area. Prioritize direct pouring or latent gates and short flows, and control shear heat and burning points.

Warpage control: Cooling should be as isothermal as possible and the gate should be symmetrical. Long strips/thin-walled parts can enhance the consistency of local cooling.

Примечание: The equipment, molds and parts vary greatly. The above is the starting window. It is recommended to use DOE to quickly converge to the best rhythm and appearance.

05 | Market Competitiveness and Industry Value

Compared with a single substrate, PC+PBT 1102 is more balanced in the three aspects of "low-temperature toughness × chemical resistance × processing stability", and is suitable for projects that have requirements for yield, appearance consistency and assembly accuracy. For factories, its replicability and the width of the molding window mean less machine adjustment time, more stable yield rates and more controllable costs. The materials are recyclable and reusable, which also aligns with the company's long-term goals in ESG and green manufacturing.

06 | Customer Feedback (Excerpt)

"During the extremely cold road test, the performance of the trim parts was stable, and the return rate dropped significantly." " -- European automotive parts supplier

"The material is easy to mold, with shallow seams, a faster injection molding cycle, and a significant improvement in yield." " -- Asian Electronic Assembly Plant

07 | FAQ

Q1: What advantages does PC+PBT have over pure PC or pure PBT?
A: By combining the high impact resistance of PC with the chemical and weather resistance of PBT, the comprehensive adaptability is broader, especially suitable for working conditions where low temperatures and chemical media coexist.

Q2: Can it be used for food contact?
A: Standard PC+PBT 1102 is not food grade. If it involves food contact or regulatory compliance, please choose a dedicated certified formula or conduct a customized assessment.

Q3: How can injection molding get started quickly?
A: Mold temperature 60-80°C, injection speed moderately high, segmented pressure holding and effective venting. The appearance parts should be given priority to ensure isothermal cooling, and then fine-tuning the holding pressure and back pressure to stabilize the surface quality.
