发明名称 Sintering polymers with narrow melting temperature range avoiding total collapse of material into a liquid
摘要 To sinter polymers with narrow melting temperature range and high melt index, at least two different portions of similar polymer type with differing melting properties are employed. Different types of polymer may be used and mixed together. One type coats the other, the former having the lower melting temperature range. Portion(s) may be mixed with radiation-absorbent additive. A portion is co-extruded and/or granulated. The portion with the lower melting temperature range lies outside.
