Description: H-PU 95 Shore A is a universally applicable sealing material, characterized above all by its wide service temperature range.
This hydrolysis-resistant material can still be used when other PUs have long since failed. It offers excellent turning, milling, and grinding properties.
H-PU delivers very good values in tensile strength, elongation at break, and tear resistance. The compression set is very low. Additional advantages include excellent abrasion resistance, high elasticity, high dynamic load capacity, and low gas permeability. It also holds FDA approval. This material is manufactured both by injection molding and casting.
Description: PU 93 Shore A exhibits similar mechanical properties to HPU. Its operational temperature range is from -30°C to 110°C.
In applications involving hydraulic fluids, oil in water emulsions (HFA, HFB), and vegetable oils, the temperature should not exceed 60°C. (If this temperature is exceeded, HPU should be preferred). This PU is produced by injection molding and has good machinability.
Description: SL-PU 55D is distinguished by very good compressive strength and low friction. This material can provide solutions particularly in applications where lubrication poses challenges. In many cases, SL-PU 55D can replace PTFE with significant advantages.
Easy installation is just one of the notable benefits of this material.
Description: SL-PU is a special polyurethane filled with solid lubricants and is primarily used for dry running applications in pneumatics.
Nowadays, many applications avoid lubricants to protect the environment. Solid lubricants reduce friction between the cylinder and the seal.
The machining properties for turning, milling, and grinding are excellent. Using this material, you can produce seals of the highest quality with our DMH SYSTEM.
Description: LT-PU Plus 57D is a hydrolysis-resistant material suitable for temperatures from -55°C to +110°C. This material is especially suitable in combination with preload elements made of soft rubber elastomers as a slide ring seal or as a scraper for heavy contamination.
Description: LT-PU Plus is a new development for even lower temperatures. Especially in mobile hydraulics, the final installation location of the systems is not always obvious.
With LT-PU Plus, you are on the safe side down to -55°C in all cases. Additionally, it is somewhat easier to machine than LT-PU.
Description: LT-PU was developed for temperatures down to -50°C. This material is also suitable for conditions comparable to Arctic climates.
With our DMH SYSTEM, you can produce seals of the highest quality using this material.
Description: C-HPU 72 Shore D is produced by both casting and injection molding and is suitable for cable rollers, roll bodies, as well as various seals and support rings.
Its machinability is outstanding. High-level turning and milling pose no problems. This material has an operating temperature range from -20°C to 110°C.
Description: C-HPU 57 Shore D is a cast, hydrolysis-resistant sealing material suitable for many applications.
This material is characterized by its excellent mechanical properties. Particularly, the lower friction is advantageous in many applications. Due to its high resistance, this material is used in high-pressure applications. Its machinability is comparable to our C-HPU 96.
Description: C-HPU 96 Shore A is our cast, hydrolysis-resistant all-purpose sealing material.
This material distinguishes itself through excellent mechanical properties. Additionally, it is FDA compliant.
Due to its high elasticity, machining is somewhat more challenging than with our standard H-PU 95. We offer C-HPU 96 in various colors. For further information, please contact our semi-finished products department.
Description: H-PU 55 D is a universally applicable sealing material, notable for its good performance over a wide temperature range.
This hydrolysis-resistant polyurethane is often used as a slide ring seal in piston and rod seals such as DK108 or DS129.
It offers many advantages compared to PTFE. Easy installation and high pressure resistance characterize this H-PU variant. Machinability for turning, milling, and grinding is excellent.
Description: HPU SOFT is an advanced development of DMH100 HPU, distinguished by excellent resistance to numerous operating fluids and providing greater elasticity than any previous PU in the DMH range. With DMH107 HPU SOFT, we offer a material that meets the requirements of pneumatics and hydraulics. An advantage over rubber elastomers is its good wear resistance (abrasion) as well as the known benefits of PU.
