Included activities starts

The activity starts with the production and import of "fibrous passenger-vehicle acoustic insulation material" in the region.

Included activities ends

The activity ends with the provision of "fibrous passenger-vehicle acoustic insulation material" to consumers of the product. Transportation is included, but product losses during transportation are negligible and therefore excluded.

Description

This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. This dataset represents the average production of passenger-vehicle acoustic insulation material in China, mainly using the melt-blown process. The dataset considers the acquisition and input of raw and auxiliary materials (polyester fiber, polypropylene fiber, non-woven fabric, etc.), energy supply, and direct emissions and process waste generation in core production processes such as synthetic/recycled fiber melting, melt spinning into fiber, web forming, compositing, edge sealing and cutting, as well as related auxiliary processes (such as waste treatment, equipment lubrication); it does not include product packaging, production equipment manufacturing, plant and other infrastructure construction; and the inventory has been supplemented and verified according to the principles of material balance and water balance. The data is mainly based on the public production materials of several industry-representative enterprises, formed after weighted integration.

Activity Description

The system boundary covers core manufacturing processes such as synthetic/recycled fiber melting, spinning, web forming, compounding, edge banding and cutting, as well as energy-auxiliary processes such as energy input and waste treatment in the factory, excluding product packaging.

Process Description

Passenger-vehicle acoustic insulation material refers to acoustic material specifically used in passenger-vehicle NVH (noise, vibration, and harshness) control systems. It can be classified by primary material system as fibrous, foam, or composite.
