Laser Marking on Silicones

Marking on silicone elastomers can be challenging. Extremely. But thanks to laser marking, even the most challenging of polymers – such as silicone cables or medical tubing – can be marked accurately and easily.

COLLABORATION WITH WACKER

In collaboration with our partner, Wacker Chemie AG – a market leader in silicone materials – we have created permanent and durable laser marking on silicone with our Iriotec® 8000 series. The target applications are typically found in the cable and tubing industry.

SILICONE ELASTOMER

Silicone rubber essentially consists of silicone polymers and fillers. The polymers are cross-linked with suitable reactants to produce three-dimensional structures that convert the fluid or ductile rubber compound into an elastomer. Thanks to their thermal and chemical resistance and inert nature, silicone elastomers are suitable for a wide range of applications, such as medical tubes, cables, and consumer products like baking molds, sports items, and leisure articles. For example, silicone cables are used as heat-stable cables or as flame-retardant safety cables in electric vehicles, but also in places like airports and official constructions.

Placing a permanent marking on products is an ever-increasing market demand – which has until now been a challenging task for silicone elastomers. Our laser-sensitive pigments Iriotec® 8000 series are changing this and are available as ready-to-use masterbatches from WACKER for liquid (LSR) and solid silicone rubbers (HTV).

Endless Possibilities
In a world where packaging transcends mere function to become an art form, the Unbox a World of Endless Possibilities campaign invites you to explore captivating inspirations for luxury packaging. The demo tool features five elegant bottles, each representing a unique blend of color and functionality.
Food Contact Safe!
For us, product safety is of utmost priority. With the Food Contact Notification (FCN) we have obtained regulatory clearance from the United States Food and Drug Administration for the majority of our industrial and laser marking pigments in plastic applications.
Our Sustainability Culture
Sustainability lies at the heart of our decision-making processes, shaping both our strategy and our culture. We embrace sustainability as a shared mission, collaborating across departments to integrate responsible practices into the very fabric of our business.
Harmonization & Verification
Global harmonization of CO2e calculation and reporting standards, combined with independant verification methods that are trustworthy and acceptable for all stakeholders, are prerequisites for sound environmental progress and a positive sustainability culture in our industries. Harmonized standards strengthen the comparability, consistency and decision usefulness of climate-related disclosures around the world.
Partnerships for Success
We understand that we cannot enact meaningful change on our own. That's why we work closely with partners across our value chain to drive collective action at scale.
Working Together Works Better
We truly believe in the power of cooperation, that supporting sustainable progress throughout our industries works better when we do it together. We're therefore actively scouting for initiatives and organizations that promote new standards and we love joining from the start as co-founders, like we‘ve been with some of these organizations.
Tracking Emissions
At Surface Solutions, we are committed to climate protection. We are focused on reducing our environmental impact, pushing best practice in line with industry standards, and communicating responsibly and transparently about our performance and our ambitions.
Environmental
Because it's up to all of us to halt the tide of climate change and protect the environment, we are cutting down our emissions, reducing our energy consumption and manage natural resources responsibly. We have formulated several goals, defined clear measures and plans to achieve them and we report regularly on our progress.
SDG
At Surface Solutions, we recognize the critical importance of the United Nations Sustainable Development Goals (SDGs) as a universal framework for addressing the world's most pressing challenges. By aligning our sustainability initiatives with these goals, we not only contribute to global efforts for a more sustainable future but also enhance our own operational practices and stakeholder relationships.
