The invention relates to metathesis polymers wherein an aromatic group that has UV-light absorbing properties is attached with a bridge group to the polymer. Capacity grids are produce by applying one of a plurality of sparing versions that designate at least one data storage block in each row of the grid is designated as spare, Defined within each capacity grid are one or more data storage units. The impact load applied to the dash panel during a frontal crash is evenly distributed to various structural parts and a favorable crash safety is achieved. The extruded material can be enclosed within a polyvinyl chloride cap layer.
