PVB Plastic Pellet Moisture
Near Infrared Moisture Sensors
PVB, or polyvinyl butyral, is an 80-year-old resin used for strong binding applications. PVB plastic pellet moisture is an essential step in the process as the materials need:
- Optical clarity
- Outstanding binding efficiency
- Toughness
- Flexibility
- Adhesion to multiple surfaces
The most common application is laminated safety glass in car windshields, although they are also used in ceramic adhesives, inks, paints and coatings, binders for magnetic media, and adhesives for metals. Scrap from PBV applications is collected and made into pellets for recycling into polymer blends. It is also used as a coating material.
Calculate Potential ROI
Why Measure Moisture?
As with any textile manufacturing process, controlling PBV plastic pellet moisture during production is critical to the product’s final quality. By measuring the moisture, the producer can ensure the quality of the end product and sell it at the appropriate price. The cost of the product is usually calculated based on the weight of the pellets, and the moisture affects this.
The moisture content varies a lot between raw materials and at different points in the manufacturing process. A moisture measurement system is critical that can:
- Measure the moisture continually
- Collect data at any point in the process
- Gets reliable, non-contact moisture measurements
non-contact
Our equipment never comes into contact with the product, allowing for less waste
zero drift
Our sensors are guaranteed not to drift over time – which saves time and money
closed loop
Create a closed-loop process by tying a moisture sensor into your PLC. Full control over the line!
no recalibrations
We’ve mastered the art of moisture sensors – your unit will never need to be recalibrated for the same product twice!
The Best Solution
Typical moisture accuracy is about ± 0.05%, with coating accuracy varying from 0.1 to 0.01 micron, depending on the coating type. A typical analog range is 0-10% moisture. The outputs can be adjusted to optimize recording requirements or PLC.
Assess
Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.
Remember this could involve more than one installation point!

Understand the Process
Using the IR-3000 drastically cuts production costs. It is energy efficient, low maintenance, and decreases startup and downtimes. Overdried product causes waste; so do products that are too moist. With the IR-3000, these problems will no longer be an issue.
