Which term describes a rubber material commonly used as the framing rubber for side windows?

• A. EPDM
• B. Elastomer
• C. Elasticity
• D. Direct Glazing

Answer: (A)

EPDM is a synthetic rubber chosen for automotive weather seals because it excels in resisting weathering, ozone, and UV exposure while staying flexible over a wide temperature range. This makes the framing rubber around side windows durable and reliable, maintaining a tight seal against water and air for long periods. Elastomer describes a broad class of elastic polymers, not a specific material; elasticity is a property of how something stretches and returns, which could apply to many materials. Direct Glazing is a method of installing glass, not the rubber material itself. So the term that names the durable rubber commonly used for that framing is EPDM.
