The invention relates to a method for welding a polyolefin plastic and a plastic using a primer, said primer containing at least one maleic anhydride containing polymer and at least one polyester. The invention also relates to correspondingly bonded products.

A consumable assembly for use with an additive manufacturing system to print three-dimensional parts, the consumable assembly including a supply device (e.g., a spool) and a filament supported by the supply device, where the filament has a composition comprising one or more elastomers and one or more reinforcing additives, and a filament geometry configured to be received by a liquefier assembly of the additive manufacturing system. The composition is preferably configured to be thermally and/or chemically modified to reduce its flexural modulus.

A method of fastening an edge structure to a construction element includes providing the construction element, being a planar structure with two cover regions and a middle region between the cover regions; providing the edge structure being continuously extended, the edge structure having contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the construction element, and, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure; coupling energy into the edge structure and pressing the contact surfaces against the cover regions until at least a portion of the thermoplastic material is liquefied and pressed into the cover regions; and repeating or continuing the steps of coupling and pressing until the edge structure is attached to the building element at a plurality of discrete locations or over an extended region along an edge of the construction element.

Provided is a method for producing a micro flow channel chip that is used for a treatment or analysis of a liquid sample, the method being capable of producing a micro flow channel chip with high shape accuracy and high efficiency. The method includes a step of forming a groove on one surface of a base material; a lamination step of forming an adhesive resin layer on at least one surface of a resin film, and thereby obtaining a first laminate; and an adhesion step of arranging the surface of the base material where a groove has been formed and the adhesive resin layer of the first laminate to face each other, and bonding the base material and the first laminate such that the adhesive resin layer covers the groove, in which the glass transition temperature of the adhesive resin layer is 25 C. or lower.

A reusable, non-adhesive protective cover is disclosed which includes a first layer having an exterior surface designed to contact a structure or object during use and a second layer having an exterior surface designed to be spaced away from the structure or object. Each of the first and second layers are formed from a thermoplastic film and are joined together to form a laminate which is free of polyvinyl chloride. Each of the first and second layers contains at least about 5% of a flame retardant. The first layer has a static coefficient of friction of at least about 0.5. The second layer exhibits attachment and release capabilities such that a joint tape can be used to join adjacent sheets of the reusable, non-adhesive protective cover together and the joint tape can be removed without damaging the reusable, non-adhesive protective cover.

Provided herein is a molding material that attains little fluctuation in amount of short fibers and powdery resin among individual products and that allows continuous production without damaging a die. In the step of pouring, slurry is poured onto a slurry diffusion member 7 from above the slurry diffusion member 7. The slurry diffusion member 7 extends in an upward direction, and is shaped such that the area of a transverse section taken along a direction orthogonal to the upward direction becomes smaller as the slurry diffusion member 7 extends in the upward direction. In the step of cleaning, a dispersion medium that is the same as the dispersion medium used in the step of pouring or water is poured onto the slurry diffusion member 7 from above the slurry diffusion member 7 to cause the short fibers and the powdery resin adhering to a slurry diffusion portion 71 of the slurry diffusion member 7 to fall down. After that, the dispersion medium is discharged from a cylindrical die 3 to accumulate the short fibers and the powdery resin in the cylindrical die 3 to obtain an aggregate 38 of the short fibers and the powdery resin. Then, the aggregate 38 is compressed.
