This is succeeding model of AF Series which k6040 many delivery result to car industries, seat manufacturers, raw materials manufacturers and public enterprises etc. The content of the polymer jie in the polyol component, the polyol relative to parts by weight of the component is preferably parts by weight, more preferably 10 to 35 mass parts. Instron testing machines can follow ASTM D and find the strength parallel or perpendicular to the grain, internal bond strength, and cleavage strength for wood.
Glossary of Materials Testing Terms. This tester can also be used to check the strength of… Wednesday April 4th, Yasuda By admin. A weight average molecular weight of 4, to 10, wherein the weight average molecular weight per functional group is a functional group 1, to 4, polyols, one terminal propylene oxide group and at least terminal ethylene oxide groups polyurethane foam according to any one of claim 1 to 7. Polyurethane foams of the present invention is not reason is uncertain having the above characteristics, it is presumed to be due to the following reasons.
Urethane Foam Tester
ASTM D Internal O6400 Test Fiberboard and Wood Adhesives For wood adhesives in wood composites, the internal bond strength test can be done with a or testing machine to determine the tensile strength.
Hereinafter will be described in detail for each component constituting the polyurethane foam. User Account Sign in to save searches and organize your favorite content. Then, by foaming the foaming stock solution in the mold and cured.
The results reveal that the constitution of the foam either open or closed cells of pores and the thickness and hardness of the cushion layer strongly affect the sound insulation performance of the floor.
Certain polyols, in view of impact resilience, weight jiss molecular weight per functional group is 1, to 4, preferably 1, to 3, more preferably 1, to 2, it is.
JIS K 6400 Foam Dynamic Roller Shear Compression Fatigue Lab Test Machine
A weight average molecular weight of 4, to 10, a weight average molecular weight per functional group is 1, to 4, of the polyol, according to any one of claims 1 to 5, which is a polyether polyol polyurethane foam.
Foam stabilizer, there can be used those commonly used as those for the polyurethane foam moldings, for example, various siloxane – can be used silicone-based foam stabilizer, such as polyether block copolymer. By foaming stock solution containing the catalyst, it is possible to enhance the reactivity at the time of foam molding.
Moldability, from the viewpoint of reactivity, block of EO units is preferably in the molecular end. AF Series is Automatic Hardness Tester for flexible urethane foams to be used for cushion materials in such products as car seat, furniture, and bedding, and for other kind of plastic foam.
Features For the load mechanism servo motor and ball screw jack are employed. The demands covering details from user are given always feed-back to development division, and it has been realized high userbility proper to the exclusive machine.
Urethane foam consists of elastic fibres with pores. Among them, from the viewpoint of increasing the impact resilience of the polyurethane foam, it is preferable to use ethylene oxide-terminated crosslinking agent.
Bluehill LE for Basic Testing. According to the present m6400, it is possible to provide a polyurethane foam and a seat pad to achieve both high resilience and high vibration absorption. For example, in the seat pad for a vehicle, vibration caused by the vehicle running, vibration absorption to absorb vibration of the engine is demanded.
The demands covering details from user are given always feed-back to development division, and it has been realized high userbility proper to the exclusive machine. Communication agent may be used as general purpose as for polyurethane foam moldings. By polyol component comprises a polymer polyol, water can be prevented from deterioration of impact resilience and hardness when used as blowing agents. Flexible polyurethane foam, process for its production, and seat for automobile employing it.
Therefore, the high resilience and high vibration absorption was characteristic of antinomy. In this paper, we propose an analytical model for use in evaluating the performance of insulation against floor impact sound. Closed cell ratio of the closed cell content the polyurethane foam was measured by the method based on the Beckman method ASTM D De Gruyter – Sciendo. Seat pad of the present invention, in the foam molding of a polyurethane foam, as the mold, can be obtained by using a mold having a shape of a desired seat pad.
Communicating k64400 Sanyo Chemical Industries, Ltd. Polyurethane foam and seat pad The present invention relates to a polyurethane foam and seat pad. Software for 6k400 Systems. Kind code of ref document: Cross-linking agent 1 a crosslinking agent 1 Asahi Glass Co.
Polymer polyols, may be a commercially available product, for example, manufactured by Sanyo Chemical Industries, Ltd. Particular polyol k64400 not particularly limited as long as it has the jid molecular weight properties, the ethylene oxide sometimes referred to as EO and polyether polyols obtained by ring-opening polymerization of propylene oxide sometimes referred l6400 as PO it is preferable that.
Flexible polyurethane foam, process for its production, and seat for automobile using the flexible polyurethane foam. Rebound resilience polyurethane foam, the resonance frequency and the vibration magnification, the density of the polyurethane foam, closed cell content, cell size, they tend jus depend on the hardness and the like.
Foaming stock solution, polyurethane foam according to claim 1 or 2 comprising ethylene oxide-terminated crosslinking agent. The evaluation results are shown in Table 1. Water from to generate carbon dioxide gas reacts with the i6400 component, which acts as a blowing agent.

Wood Tension Fixtures Instron testing machines can follow ASTM D and find the strength parallel or perpendicular to the grain, internal bond strength, and cleavage strength for wood. The resulting polyurethane foam was evaluated by the following method.
On the other hand, the vibration-absorbing polyurethane foam is generally due to the breathability of the polyurethane foam.
