Composite Solution
Composite Solutions for Sanitary Ware
Material-selection support for sanitary ware and related bathroom composite production, aligned with the actual forming, reinforcement, surface and cycle requirements.
Application Scope
Sanitary ware production may combine thermoformed acrylic shells, composite backing, moulded sections or mineral-filled surfaces. Resin-family selection depends on the finished-product structure, application method, mould and release conditions, target surface and production cycle.
SIHE reviews the customer's product and representative production conditions before confirming the resin grade for supply.
Typical Products and Production Scenarios
Typical finished products
- Bathtubs and shower trays
- Washbasins and sanitary composite parts
- Thermoformed acrylic shells requiring composite reinforcement
- Related bathroom surfaces and moulded components
Production scenarios
- Backing or reinforcement of formed sanitary shells
- Moulded sanitary components and representative trial parts
- Process review before scale-up or material change
Application and process reference
Customer cases
SIHE288 is used for common sanitary ware products made by hand lay-up and spray-up. The following two bathtub production projects show how SIHE supplied resin and production guidance matched to each customer's production conditions.
Case 1: Bathtub production by hand lay-up
One bathtub manufacturer using hand lay-up had previously used resin from another supplier at a resin-to-stone-powder ratio by weight of 1:0.1. The customer reported that the relatively high resin usage increased production costs and that noticeable sagging occurred.
SIHE supplied SIHE288 resin and provided production guidance. The customer used it in hand lay-up bathtub production in line with its established operating practices and adjusted the resin-to-stone-powder ratio by weight to 1:0.7. According to the customer's feedback, production costs decreased after the adjustment, the resin viscosity better suited its operating needs, fibre wet-out was good, and sagging was markedly reduced compared with the previously used resin.
Case 2: Bathtub production by spray-up
Another bathtub manufacturer using spray-up had previously used resin from another supplier at a resin-to-stone-powder ratio by weight of 1:0.9. The customer reported high production costs with the previous material setup. It also reported that the previously used resin reached a high peak temperature during curing and that heat from curing had damaged bathtubs on several occasions.
SIHE supplied SIHE288 resin and provided production guidance. The customer used it in spray-up bathtub production under its own production conditions and adjusted the resin-to-stone-powder ratio by weight to 1:1.2. The customer reported lower production costs after the adjustment. For the production period covered by this feedback, the customer reported no further bathtub damage from curing heat while using SIHE288, along with less rework and product damage.
Across these two projects, SIHE has tailored its process adjustment support to the customers' production conditions and the operators' adaptation to the process, addressing each project's specific production needs. SIHE currently maintains stable, long-term cooperation with both customers.
Common Production Goals and Challenges
- Achieving the required visible and backed-surface finish
- Matching resin application and wet-out to the reinforcement method
- Maintaining a workable gel and cure window for the production cycle
- Managing shrinkage, warpage and demoulding behaviour
- Keeping representative production results consistent between batches
Information Needed for Material Selection
- Finished-product type, such as a washbasin, shower tray, bathtub or other sanitary product
- Current production and application process
- Product dimensions, construction and reinforcement structure
- Visible and backed-surface requirements
- Forming, mould and demoulding requirements
- Target production cycle and available working window
- Current material and the production problem to be reviewed
- Estimated demand and destination country
Material Requirements
- Application and wet-out behaviour suited to the reinforcement process
- A gel and cure window aligned with the actual part and production cycle
- Shrinkage and dimensional control suited to the product construction
- Surface and finishing behaviour assessed against the target product
- Compatibility with the customer's mould, reinforcement and current process after trials
Recommended SIHE Products
SIHE Resin Series for Acrylic Sanitary Ware
Resin for reinforcing acrylic sanitary ware and for thermoforming specially shaped artificial-stone products.
- Why consider this product
- A current SIHE resin-family direction for reinforcing thermoformed acrylic sanitary ware and related sanitary products where surface finish and process control must be considered together.
- Confirm before selection
- Confirm the finished-product structure, reinforcement method, application process, mould and release conditions, surface target, production cycle and trial criteria.
This product entry represents a resin family rather than one fixed formulation. The listed grades and typical parameters support preliminary selection. SIHE confirms the actual delivery grade according to the application and production process.
How SIHE Supports Material Selection
Share the finished-product, application and production-process requirements.
SIHE reviews the production conditions, current materials and reported problems.
SIHE identifies candidate product families or grades for representative evaluation.
Quotation, sample and document availability are confirmed according to the reviewed request.
The automatic acknowledgement only confirms that the RFQ was saved. It is not a quotation, sample approval, inventory or delivery confirmation, or a final technical conclusion. Product and delivery-grade selection is confirmed by a SIHE representative after review.
Technical Documents and Samples
Controlled technical documents
General product information may be shown publicly. Current TDS documents are supplied through a controlled request, while SDS availability is reviewed for the selected product and market of use. SIHE does not promise that every grade has a current document in every requested language.
Manual sample review
Every sample request is reviewed manually. Availability, sample size, charges and shipping method are confirmed against the product, application, test plan, estimated demand and destination.
