PROJECT KICK OFF
B R I E F
Application: Protective sports equipment
Challenge: Provide functional material to protect
against impact for chest protector
Requirements:
• Compact - reduce thickness and weight for
improved comfort and functionality
• Meet EN standards
• EN1621-1 level 2 & EN1621-2 level 1
• Eliminate the use of foam and glue
• Be waterproof and easy to clean
• Sustainable
• Easy to prototype & considers manufacturing
efficiency

Simplified Drop Test
• 65g steel ball
• Dropped from 305mm
• Onto 3.175mm thickness flat
samples
Materials Tested
• Standard TPE 30 Shore A
• TPU alloy 60 Shore A
• Damping TPE 32 Shore A
VDT reduces
bounce

• A number of different shapes and
designs are created and simulated to
determine which one works best
• Refining to meet EN standard
• VDT TPEs can help reach compliance
with EN1621-1 level 2 and EN1621-2
level 1
• Optimum protection can be achieved
by combining industrial design and
engineering
