Precision at Every Step - the Art and Science of Material and Compound Selection

Step 1 - Understanding Challenges, Defining Solutions

The journey toward delivering cutting-edge materials starts with an in-depth understanding of the unique challenges faced by our customers. From extreme temperatures and exposure to aggressive chemicals to mechanical stress and regulatory compliance, our engineers assess every aspect of the application to define the precise material properties required.

Step 2 - Thorough Research and Development

Our R&D team combines decades of expertise with advanced analytical tools to develop high-tech elastomeric and non-elastomeric compounds. Whether working with advanced elastomers like PERTEC® or high-performance plastics such as PTFE, we ensure each formulation is optimized for durability, reliability, and efficiency. This includes compliances checks for regulated industries and other challenges as well. As an example, we follow the current PFAS discussion carefully.

This development process includes:

Evaluating raw materials through detailed chemical and physical inspections.
Conducting comprehensive laboratory and application-specific testing.
Leveraging advanced production technologies, such as automated ingredient dosing and high efficiency mixing machinery, for consistent quality and performance.

Step 3 - Precision Testing for Optimal Results

Every high frequency compound undergoes extensive testing, far beyond typical industry compliance standards. Using sophisticated techniques—including thermogravimetric analysis, calorimetric testing, and surface morphology assessments - we evaluate critical performance factors such as chemical resistance, mechanical stress behaviour, and long-term durability.

Turning Challenges into Triumphs: Customer Success

Fast Results Thanks to Experience, Design Skills and Material Knowledge

Warmhaus, a leading global producer of radiators and boilers, sought to develop silicone control buttons for its combi-boilers. These buttons needed to combine functionality, durability, and visual appeal for domestic installations while aligning with the company’s reputation for award-winning design innovation.

Challenge:
The buttons had to meet high standards for responsiveness, surface aesthetics, and thermal resistance, while coordinating with the boiler's design. Compounding the challenge, Warmhaus aimed for an ambitious market launch, requiring rapid prototyping and material approvals to ensure serial production began on time.

Solution:
Angst+Pfister’s engineers leveraged their extensive expertise in material science, design, and efficient development methods.

Silicone control buttons of a Warmhaus combi boiler

The team created silicone-based control buttons tailored to Warmhaus’s specifications, including conductive elements and a “reset” function. The design integrated seamlessly with the boiler’s housing and color scheme. Rapid prototyping and material testing ensured production deadlines were met without compromising quality.

Result:
Warmhaus launched its boilers successfully, featuring high-performance, visually appealing control buttons that met stringent functionality and durability standards. Warmhaus praised Angst+Pfister as a valuable partner capable of delivering market-specific, high-quality rubber components under tight time constraints. This collaboration reinforced Angst+Pfister’s reputation for reliability, innovation and customer-focused solutions.
