High-Clarity PVB for Electrochromic Dynamic Tinting Glass

The future of solar control is dynamic. Our High-Clarity PVB for Electrochromic Glass is specifically engineered to laminate advanced electrochromic films (which change from clear to dark blue/grey when low voltage is applied). Unlike PDLC (which goes milky for privacy), electrochromic glass is used to actively manage glare and heat. This PVB provides the perfect, low-temperature, ultra-clear encapsulation required to protect these sensitive active materials.

Key Advantages & Benefits

  • Active Film Protection: Processes at optimized temperatures to prevent thermal degradation of the delicate electrochromic nano-coatings.
  • Perfect Clarity: Ensures the glass remains flawlessly clear when in the untinted state, with zero haze or yellowing.
  • Moisture Barrier: Provides a robust edge seal, preventing moisture from short-circuiting the electrical current running through the smart film.
  • UV Protection: Blocks 99% of UV rays, protecting both building occupants and the internal active film from UV degradation.

Versatile Applications

  • High-end commercial office facades and curtain walls
  • Luxury automotive panoramic sunroofs (active dimming)
  • Aviation cabin windows (button-operated tinting)
  • Premium residential skylights and sunrooms

Frequently Asked Questions (FAQ)

Q: What is the difference between this and your PDLC Smart PVB?
A: PDLC goes from clear to opaque (milky white) for privacy. Electrochromic goes from clear to dark tinted (like sunglasses) for glare and heat control. Both require specially formulated, low-temperature PVB, but are optimized for different smart films.
Q: Does it require wiring?
A: Yes, the glass processor will encapsulate the electrical busbars along the edge of the glass using this PVB, which connects to the building's electrical and control system.

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
