Product Description

Product Description

Material: closed-cell PU elastomer (Polyurethane)

Color: dark green

Dimensions can be customized,Other dimensions, punched and moulded parts on request.

Thermotest is using "Sylodyn," a polyurethane dampening material developed by Getzner, a company with worldwide success in railroad and construction, in subway, railway, and highway soundproofing and dampening. Compared to existing dampening rubber, Sylodyn is more durable, more stable and is able to be made thinner in order to fit into small spaces, making installation quick and easy.

² The measurement is performed on a densitydependent basis with differing test parameters
³ Values apply to shape factor q = 3

 

· Quasi-static load deflection curve measured with a loading rate of
0.3 N/mm²/s.

· Testing be tween s andblasted, flat steel-plates; recording of the 1st load, with filtered starting range in accordance with ISO 844, testing at room temperature.


· Shape factor q = 3

· Quasi-static modulus of elasticity as tangential modulus from the load deflection curve. Dynamic modulus of elasticity from sinusoidal excitation with a velocity level of 100 dBv re. 5 · 10-8 m/s corresponding to a vibration amplitude of 0.22 mm at 10 Hz and 0.08 mm at 30 Hz.

· Measurement in accordance with DIN 53513

· Shape factor q = 3

· Natural frequencies of a vibratory system with a single degree of
free dome, consisting of a mass and an elastic bearing made of
Sylodyn® HRB HS 3000 on a rigid surface.

· Parameter: thickness of the Sylodyn® bearing

· Shape factor q = 3

 

· Deformation under consistent loading.

· Parameter: permanent static load

· Shape factor: q = 3
 

 

 

· Typical dependency of the dynamic modulus of elasticity on the
amplitude of vibration.

· Sylodyn® HRB HS 3000 materials exhibit a negligible dependency of
amplitude.
