    Abstract: The purpose of the present invention is to provide a polyester resin composition for a reflection plate having high reflectance and small decrease of reflectance under exposure to heat during production of an LED package or reflow soldering step for mounting, or exposure to heat and light from a light source. A polyester resin composition of the present invention contains: 30-80% by mass of (A) a polyester resin having a melting point or glass transition temperature of 250 °C or more as measured by DSC; 5-30% by mass of (B) a fibrous reinforcing material having an average fiber length (1) of 2-300 µm, an average fiber diameter (d) of 0.05-18 µm and an aspect ratio (1/d) of 2-20, said aspect ratio being a quotient of 1 by d; and 5-50% by mass of (C) a white pigment (with the total of (A), (B) and (C) being 100% by mass).

    Abstract: The present invention relates to a valve member for a dispenser valve for foam products, and in particular for a dispenser valve for polyurethane foam container, comprising a valve member that is moveable relative to a sealing. It also relates to such a dispenser valve and to a foam container. In order to provide alternative materials for valve members, it is proposed according to the invention that the valve member is made of plastic material filled with mineral particles in an amount between 1 % and 60 % by weight. It has been surprisingly found that valve members made of plastic filled with mineral particles in these amounts show improved properties, such as strength and abrasion rates, compared to non-filled plastics and compared to glass-filled plastics.
