Tacky Gels for Healthcare Applications

Silicone tacky gels are ideal for processing into sheets or pads for various topical applications requiring a temporary adhesive. Some key examples include:

• Wound care
• Scar management therapies
• Transdermal therapeutic systems
• Face masks
• Ostomy and incontinence care products

Silicone gels have a history of biocompatibility, are non-allergenic, and offer superior breathability. In addition, dimethyl silicone tacky gels provide the best moisture permeability on the market, demonstrating Water Vapor Transmission Rates (WVTR) values of up to 68 gm/m2/day.

The advantages of using a silicone gel system are:

• Solvent-free
• Modifiable tack
• Varying viscosities
• Adjustable cure profiles
• Cohesive Strength

Understanding Silicones in Controlled Release Applications

As one of the most widely researched biomaterials to date, silicone has an approximate 50-year legacy of use in the healthcare industry. This history of biocompatibility has made silicone a material of choice for both long and short-term implantable device applications. These technologies evolved as the result of pharmaceutical and medical device manufacturers seeking novel ways to achieve their therapies. So, raw materials that were formerly chosen for their performance capabilities in medical device applications are now tasked with maintaining those requirements but also with meeting a host of new performance expectations that are specific to drug delivery applications. Faced with these new challenges few raw materials have succeeded in transitioning quite as well as silicone. This is because silicones possess certain dynamic characteristics which allow them to be compounded in with a host of actives. These same unique characteristics also allow them to release those actives from a molded/extruded device in a predictable way – whether that application is for transdermal, transmucosal, short or long-term human implantation. This article will highlight key attributes of certain silicones as well as key considerations when selecting a silicone.

Methods Used to Sterilize Silicone

The majority of sterile goods produced in the medical device and healthcare industries are terminally sterilized to remove unwanted microbial contamination. There are several sterilization methods commonly used for medical devices including: dry heat, steam autoclaving, ethylene oxide, gamma radiation and electron beam sterilization. Several concerns arise about the effects sterilization has on material properties including silicones….

Ultra Low Outgassing™ Silicone Materials

Silicone adhesives and coatings have been used for over five decades because of their ability to retain elasticity and low modulus over a broad temperature range, thus reducing shear stress during thermal cycling. These properties provide excellent utility in space and terrestrial environments, where spacecrafts and sensitive electronics are repeatedly exposed to these extreme temperatures.

Ultra Low OutgassingTM silicones are also excellent for reducing the risk of contamination to increase the operation life in sensitive electronics and optical applications.
