New: ELASTOSIL® LR 5471
Self-bonding LSR without thermal post-curing
AI generated
At COMPAMED, Wacker Chemie AG will be introducing ELASTOSIL® LR 5471, a self-bonding liquid silicone rubber for sensitive applications. This grade ends the need for post-curing in many cases.
Products made from ELASTOSIL® LR 5471 exhibit high transparency and excellent mechanical properties, in particular a high tear strength in accordance with ASTM D 624 B (Crescent). The ability to meet regulatory requirements for specific food-contact and babycare applications without the need for post-curing offers key advantages in terms of cost-savings and productivity.

Transdermal active delivery from silicone gel adhesives

If transdermal delivery is a topic for you: Meet us! Our experts from the WACKER Health Care Competence Center in Ann Arbor, USA have conducted a product development study.
Transdermal patches are increasingly being used for non-prescription and cosmetic applications. WACKER therefore focused on developing silicone gels that can be used for administering the most common substances.
The goal was to achieve maximum and tailored release properties while maintaining the structural integrity of the adhesive coating. The active compound was embedded to a silicone gel matrix that is a maximum 300 micrometers thin.
More than 20 active ingredients have been tested:

Q&A silicones for medical applications
2. How can I achieve longer wear time on the skin with soft silicone adhesives?
WACKER SILPURAN® skin adhesives may not achieve the same adhesive strength as aggressive acrylic adhesives, but wear times can be impressively long compared to commercially available “sensitive” acrylic systems, depending on individual conditions and the type of dressing. Wear time can be prolonged by selecting a strong silicone adhesive like SILPURAN® 2114 or SILPURAN® 2122.
3. Can wearables attached with silicone adhesives be cleaned and reused? How do I apply silicone adhesives to my device?
Yes, wearables attached with SILPURAN® silicone adhesives be cleaned and reused. For easy-to-handle products, we recommend separating the fixation element from the medical device in the product design. This makes it very easy to clean the product and replace the adhesive elements.
4. Are there High Consistency Rubber types especially suited for “Pharma Tubing“?
Our ELASTOSIL® R plus 4305 series is perfectly suited for the extrusion of tubes used in the production of pharmaceutical products. The addition curing material shows very good mechanical properties and is biocompatible. ELASTOSIL® R plus 4366 is the material of choice, where reduced friction is required to make the end application easier, e.g. where silicone slides over another surface. Therefore, it is especially suited for peristaltic pump hoses. Another grade targeted for the use in peristaltic pump hoses is ELASTOSIL® R plus 4360 with high rebound resilience and low compression set.
5. Why is ELASTOSIL® LR 3078 ideal for the 2K-production of medical multicomponent parts?
ELASTOSIL® LR 3078 enables considerable advantages when it comes to the large-scale production of multicomponent medical-technology parts: first, the material bonds reliably with polycarbonate, polysulfone and other high-performance thermoplastics in 2K production process. Second, our self-adhesive technology makes pretreatment unnecessary.
6. Is there self-adhesive liquid silicone rubber that reliably bonds with polycarbonate, polysulfone or other high-performance thermoplastics?
Yes, our ELASTOSIL® LR 3078 easily bonds with above mentioned high-performance thermoplastics, even without pretreatment. That’s a huge benefit, especially in cost-effective large-scale production of medical-technology parts such as respiratory masks, drug delivery systems or devices for minimally invasive surgery.
