Full sun. No sweat.

Saflex® S Series solar-absorbing interlayers blocks solar heat and UV radiation transmitted through a vehicle’s glazing, so driver and passengers won’t break a sweat.

This advanced automotive solar control interlayer is an easy drop-in solution with a positive chain reaction:

• lowers interior temperatures quickly
• minimizes strain on the vehicle’s air conditioner
• improves fuel efficiency

All while optimizing occupant visibility.

High marks on energy savings

Testing conducted by the National Renewable Energy Laboratory determined that a windscreen made using the Saflex S interlayers  can reduce cabin temperatures up to 5°C (9°F). This translates to a potential four percent reduction in air conditioning power versus a conventional windscreen. That reduction in air conditioning translates to a fuel efficiency improvement greater than one percent.

On a per vehicle basis, these improvements are excellent.  Across an entire fleet of vehicles, the impact can be astounding.  

Reduce infrared waves

Wavelengths from the sun called Infrared (IR) light are responsible for generating excessive heat in vehicle interiors. Compared to windscreens made with standard interlayers, Saflex S series solar-absorbing interlayers provide measurable heat reduction in the passenger cabin of stopped or slow-moving vehicles by absorbing the heat-causing IR rays without compromising visibility.  

S Series products use more effective nano-particles for solar absorbing. They provide the best solar absorbing performance in the market and are best suited for side and back windows, and sun roofs. Due to the broad absorbance spectrum, S series products might not compatible with selected IR sensors. Please contact your representative for more information. Saflex® Solar Connect is the standard choice for windscreen applications because they allow the freedom for sensor use in conjunction with a solar product.

Safety First

When it comes to passenger safety in the automotive industry, laminated glass can be a game changer. Whether addressing rock impacts, collisions or rollovers, innovations are always in the works.

Saflex® K Series high-security interlayer is an advanced, composite PVB interlayer that is stronger and more resistant to tearing and penetration than traditional interlayers. Fabricated to provide reduced flexibility if broken, Saflex high-security interlayers help mitigate the risk of ejection during rollovers and accidents for passengers seated next to row windows.

Helps Meet NHTSA Regulations

Laminated glass made with Saflex high-security interlayers can be a vital component of an integrated occupant protection system for multi-passenger vehicles or buses. Saflex K Series can help automakers meet National Highway Traffic Safety Association (NHTSA) ejection mitigation regulations (FMVSS 226), especially in fixed-glass positions and applications facing challenges with airbag tethering.

Added Benefits, Too

Saflex K Series high-security interlayer provides other forms of protection, including acoustic and solar. Noise levels in the vehicle cabin can be reduced by up to 3 dB due to its insulating benefits against outside noise. Passengers and interiors are protected from sun damage due to its ability to block out harmful UV rays. In addition to mitigating the risk of fabric and leather damage, Saflex has been shown to have a sun protection factor greater than SPF 50 sunscreen.

Clearly Better Sound Quality

Bluetooth technology, voice-activated commands, onboard navigation systems, and sophisticated audio equipment make driving more enjoyable, yet they dial up the interior noise.   A new advanced Saflex® Q Series acoustic interlayer addresses this problem with precise acoustic control.   

Saflex Q Series is an advanced tri-layer polyvinyl butyral (PVB) interlayer that reduces noise level by 4.7 dB versus a standard windscreen and 5.9 dB compared to tempered side windows within the medium frequency range (1,000 – 5,000 Hz).

The Clarity is Real

Saflex Q Series advanced acoustic interlayers are especially effective within the frequency of human key voice recognition ranges (2,000 – 6,000 Hz), reducing sound transmission by 4.8 dB over this range. In other words, consumers can hear a difference, and that can speak volumes about brand experience and perceived quality.

Lightening the Load

In response to regulatory and consumer demand for greater fuel efficiency, automotive makers rely on every opportunity to reduce overall vehicle weight. Saflex Q Series helps reduce the negative trade-offs of typical weight reduction efforts by enabling improved acoustics, even in thinner glass configurations.

Saflex Q Series enables improved acoustics in when paired with thin glass.

This solves the weight issue… For a typical windscreen, the reduction of glass thickness from 2.1/2.1 mm to 2.1/1.6 mm would result in a weight savings of 1.7 kg (3.7 lbs) or 11%.  In a standard windshield, this would result in an acoustic performance loss of 0.6 dB over the full frequency range (200 – 10,000 Hz).  However, when Saflex Q interlayers are used in the thinner configuration, the weight reduction can be achieved while still improving acoustic dampening over the standard windshield by 1.2 dB over the same frequency range.  

The addition of acoustic front side glass (2.1/2.1 mm) can enable a further reduction of 1.1 kg (2.4 lbs) while improving sound transmission loss through the side windows by 3.3 dB versus 5 mm tempered glass.  Across all glazing positions, Saflex technology allows automakers to use thinner glass without sacrificing cabin comfort.

Lightweighting also helps auto manufacturers meet global environment regulations for lower CO2 emissions, including the Kyoto Protocol, the Economic Commission for Europe (ECE), and U.S. Corporate Average Fuel Economy (CAFE) standards.
 

Avoids Retooling Costs

Typical weight reduction solutions can require expensive retooling. Automotive glazing made with Saflex Q Series can be substituted into a vehicle’s existing glass with no need for expensive redesign, retooling, or research and development.

Applications:

Windscreen, Side Window, Sunroof, Back Glass, Quarter Glass

Product Benefits:

• Improves acoustic comfort: Reduces exterior noise by up to 4.7 dB versus standard laminated glass
• Reduces weight: Enables the use of thinner glass configurations with minimal compromise to cabin acoustics
• Provides UV protection: Blocks more than 96 percent of harmful UV radiation
