MODIPER® AS155
About the Product
MODIPER® AS155 is a high-molecular-weight anti-squeak additive developed using NOF’s graft polymer technology. It is designed to suppress squeak noise generated by sliding and contact between plastic components and other materials.
Structure
- High-molecular-weight graft polymer additive
- Lubricating layer–forming design
- Halogen-free formulation
Features
- Effectively reduces squeak noise caused by stick-slip behavior
- Forms a stable lubricating layer at contact interfaces
- Works under both compounding and dry-blend processing conditions
- Supports environmentally conscious material design
Applications
- Noise-sensitive plastic components
- Interior and surface-contact resin parts
- Applications requiring squeak noise suppression
Concept of anti-squeak property about MODIPER® AS series
In case of resin without MODIPER® AS, squeak problem occurs because there is no lubricity between resin and counter material. However, in case of resin with MODIPER® AS, the squeak problem can be eliminated due to the lubricant layer which is made by MODIPER® AS.
Test method (Stick-Slip test)
The two specimens (big and small) are prepared. Big one (Test material) is reciprocated and rubbed with small one by 3 times. The risk of squeak noise is shown by Risk-Priority-Number (RPN) which is ranked by the 10 stages shown below, (In case of RPN=1～3, it is categorized as No stick-slip risk).
Test Results
<MODIPER® AS155>
Anti-squeak properties of MODIPER® AS155 are shown below with the Stick-Slip test data between PC/ABS against each other, also between PC/ABS and PVC leather. MODIPER® AS155 can show excellent anti-squeak property with adding condition not only at compounding step but also at the press.
