PBT Sheets (Hydex® 4101)
Pbt Sheets Hydex®
4101 is a polyester that is less brittle, more chip resistant, and easier to
machine than PET. PBT has the strength & wear resistance of general purpose
nylon, and a higher continuous use temperature (240° F) It is FDA/NSF/3A
Compliant.
Applications
•Food processing piston pump and valve body
•Can transfer mandrel |
Hydex®
4101 is a long wearing
alternative to Acetal in food
processing applications. |

4101 & HYDEX® 4101L
The
next revolution in Stock Shape Plastics has just arrived...Hydex 4101 and Hydex
4101L (internally lubricated) represent a family of stock shape plastics with
elevated performance over PET-P, Acetal and Nylon. Hydex 4101 is a PBT Polyester
with an outstanding set of properties that include; wear resistance, chemical
resistance and toughness. Hydex 4101L (Lubricated) is an enhanced version with
improved wear, PV range and lubricity over Hydex 4101. In direct comparison to
other commonly used plastics, Hydex 4101 and Hydex 4101L have:
Improved
Wear and Chemical Resistance Versus Acetal
- Hydex
4101 and 4101L are compatible with chemicals having a pH range of 2.0 - 9.0,
Acetal's range is 4.0 to 9.0
- Hydex
4101 and 4101L can with stand repeated "CIP" chemical washdown
without affecting material performance. Acetal degrades upon repeated
contact with aqueous chlorine solutions.
- Hydex
4101L has 30% higher limiting PV than Delrin AF
- Hydex
4101L has about two times better wear factor than Acetal
- Hydex
4101L is approved for direct food contact, Delron AF is not
Superior
Dimensional Stability Over Nylon
- Hydex
4101 and 4101L have moisture absorption of 0.07%
- Nylon
has moisture absorption 15 times greater than Hydex, and can exhibit
significant dimensional changes in use
Best
Wear and Lubricity When Compared to PET-P
- Hydex
4101 and 4101L have 20% greater impact strength than PET-P
- Hydex
4101L has about 50% better wear factor than PET-P
- Hydex
4101L has more than twice the LPV performance than PET-P
- Hydex
4101L has 50% lower coefficient of friction than PET-P
